Our extensive product range includes industrial valves from leading international manufacturers for almost all applications and areas of use.

Kugelhähne-ICP-3tlg-Kugelhahn
Ball valves

We are used in a variety of ways.
For reliable on/off and control applications.

Our wide selection of metal and soft seated ball valves ensures the best leakage rates in a wide range of applications.

Low pipe resistances, high surface quality and materials such as ceramic, PTFE or Hi-Co make our valves resistant, even with abrasive media.

Our ball valves are available in all common nominal diameters, connection types and standards (DIN and ANSI) and carry the most diverse certificates.

Kugelsegmentventile-Somas-KVTF_DN200_PN10
Ball segment valves

We work economically.
For a linear control characteristic at a high flow rate.

Somas ball segment valves are used wherever processes place the highest demands on a valve, such as in a digester during pulp production. The valves are flow-optimised to prevent deposits, work more efficiently due to their small nominal diameters and, in combination with a pneumatic actuator and positioner, form a flexible unit with a large, precise control range and excellent tightness.

Absperrklappen-Quadax-4-fach-exzentrische -Hochleistungsklappe-840x400-112
Butterfly and control valves

We are eccentric.
For high performance and no maintenance.

In addition to centric butterfly valves for simple applications (e.g. water, low cellulose content), our eccentric butterfly and control valves are used wherever peak performance is required. They offer reliability and excellent tightness at high pressure, extreme temperatures, high fibre content and high Kv values, while at the same time offering high resistance to aggressive media.

Our double and triple offset eccentric butterfly valves are also characterised by low wear, no friction and no maintenance. The Quadax© four offset eccentric butterfly valve reliably retains its tightness even at the most extreme high and low temperatures.

Plattenschieber-Orbinox-EB
Knife gate valves

We put a stop to everything.
Reliable shut-off operations with high contents of solid and suspended matter.

Knife gate valves are used where butterfly valves reach their limits, such as in the waste water sector and in sewage treatment plants, in the chemical industry or in mining. They work effectively with sludge, bulk material, waste water and contaminated or viscous media.

Materials like stainless steel and higher-grade steels prove their worth in corrosive and abrasive media.

With 50 years of experience in the pulp and paper industry, Orbinox products are equipped for the toughest process conditions.

Knife gate valves are particularly suitable for fibrous media, while reject valves cannot be affected by solids.

Absperrschieber-Wakmet-DIN-Hochdruck-Metallischdichtend
Gate Valves/ Wedge gate valves

We drive a wedge in between.
For minimal pressure drop.

V-shaped wedge gate valves are optimised for fully open or closed conditions and provide a free flow with low flow resistance at all pressure stages. As metal seated or rubberised variants, they are mainly used in water, steam, waste water, chemical, oil and gas applications.

Whether wedge gate valves or oval valves – a wide variety of models, connection types, approvals as well as the DIN or ANSI version – our manufacturers JC, Bombas Borja or RT-Valvole offer a wide range of applications.

Rückschlagklappen-Chemvalve-Doppelfügelrückschlagklappe
Check valves

We don’t swim against the flow.
For tightness in the opposite direction to the flow.

Our check valves are used in all industrial processes, especially in the pulp and paper, water treatment, chemical and food sectors.

A large selection of manufacturers gives us the opportunity to offer valves tailored to the project: from simple designs and price-performance winners to very robust variants, Orbinox, Chemvalve Schmid, Erhard, Bombas Borja, JC or RT offers the right check valve in our range.

Sicherheitsventile-Tosaca-DINxANSI-Niederdruckbereich
Safety valves

We relieve pressure.
For reliable protection of your investment.

30 years of experience deliver safety: As a specialist manufacturer of safety valves, Tosaca offers a comprehensive standard range with a wide nominal diameter range made of different materials for customers in the chemical or petrochemical industry, the pulp and paper industry and many other process applications.

Tosaca pressure relief and safety valves comply with all international and regional standards, respond reliably in overpressure conditions and therefore protect downstream valves and measuring equipment.

Schmutzfänger-Wakmet-DIN-metallischd
Strainer valves

Nothing can get by.
For effective protection against damage from foreign bodies.

In particular in the areas of fresh water supply, water treatment and water distribution, in dams and power plants and industry, strainer valves prevent the unwanted ingress of foreign bodies and therefore protect valves, control valves and measuring equipment.

A long product life cycle and low maintenance costs make these valves profitable. Low pressure loss and adequate maintenance access are a prerequisite for their use.

Ringkolbenventile-Erhard-RKSxRKV
Needle valves

For minimum cavitation and maximum protection of your plant components.

Erhard valves optimise the flow through decreasing ring cross-sections in such a way that cavitation damage is prevented and the service life of the valves is considerably increased.

The single-piece needle valves provide safe regulation of pressure stages and flow rates with linear control characteristics.

The valves that are equipped with additional corrosion protection are mainly used in water applications.

Sitzkegelventil-JC-ANSI-Absperr-Regulierventil-StopfbuchspackungFaltenbalgabdichtung
Globe valves

We provide individual regulation.
For the precise control of process control stages.

Whatever your process needs, we get it regulated, even under the most difficult process conditions: Whether with a control cone or as a globe valve version, manually operated or automated, the wide range of straight way, angle or three-way valves is available in a wide variety of materials, for all pressure stages and in the common DIN and ANSI standards.

The individual adaptation of the globe valves from our manufacturers Badger Meter, Wakmet or LDM to the respective task brings precise control accuracy in a wide control range.

Feststoffhaltig-RF-Schlauchquetschventil
Pinch valves

We are made for tough applications.
For a tight seal with minimal friction resistance.

Whether emulsions, sludge, dusty or gaseous substances, compressed air, powders, granulates, pellets, etc. – RF’s pinch valves reach their full potential wherever abrasive, corrosive or fibrous products are to be shut off or regulated.

When open, the valve ensures a free flow rate – to ensure no deposits and minimal friction resistance.

Advanced technologies ensure a long service life for the hose sleeve, which is optimised for maintenance via a wear sensor and is extremely easy to use because it can be replaced in its installed condition.

The valves can also be easily installed in existing pipes or replace existing valves

Probenahmeventil-Guichon-Pharma-655M-616M
Sampling valves

We take it all out.
For safe process analysis.

Sampling systems must ensure cleaner and safe intervention in the closed production process. In the case of our manufacturers Orbinox, JC and Guichon, samples are extracted from pipes or tanks with the most different operating principles (ball valve, piston or ball construction).

This selection allows our customers to find the right system for them. JC’s special solution is particularly suitable for long-fibred media, media containing solids or powders and is mainly used in the pulp and paper industry.

Keramikkugelhahn-Cera-System
Ceramic valves

We are the hardest.
For high wear resistance.

Fully or partially lined ceramic ball valves, disc valves and pipe wear protection parts are useful when high pressure, temperature, abrasion or corrosion places excessive stress on conventional valves.

Ceramic components increase the service life of control and butterfly valves exposed to abrasive, corrosive or solid media such as flue ash, limewater, lime mud, kaolin and other acids and alkalis.

Bodenablassventiel-Guichon
Bottom outlet valves

We embody the pure emptiness.
For efficient and safe tank emptying.

Bottom outlet valves are used in particular for highly viscous media, for powders, gas, liquids with high solid content or wherever hazardous media, high pressure or high temperatures are prevalent. Wherever deposits are critical, piston valves provide a cavity free option.

With a large variety of materials and the corresponding accessories, the bottom outlet valve can be adapted to any situation and plant.

Membranventil-Erhard
Diaphragm valves

Even the hardest lumps are powerless against our gentle embrace.
For tightness and durability with media containing solids.

Diaphragm valves remain robust even under the highest chemical stress. Their elastic diaphragm encloses solid parts and seals reliably. At the same time, wear is kept to a minimum.

Diaphragm valves are therefore used wherever contaminated or solid media and salty water are used or chemical resistance is required.

Diaphragm valves with a free bore keep flow turbulence as low as possible and reduce the space where the product can settle or deposit. Diaphragm valves are therefore also very easy to clean. The additional FDA certification makes them suitable valves for the food industry.

Valves by function

We get this arranged.
No matter how high the switching cycles may be, our on/off valves always open and close reliably, manually or automatically, just as you like. However, there are even more intelligent solutions: Our control valves provide stable processes and therefore ensure smooth processes and a high level of production efficiency.

On-Off-JC-ballvalve-515-530
On/off valves
Tight and resistant. For smooth and safe operation with the no leakage. Whether the on/off valves are designed as manual valves or with an actuator, they must guarantee absolute and long-lasting tightness when closed and low flow resistance when open. High-quality on/off valves are characterised by a long service life and ease of maintenance, even in an application with high cycles. This reduces costs and effort.
-Somas-Kugelsegmentventil-KFWT-D
Control valves
No room for deviations. For stable processes and high performance during processes. Control valves are an essential component in every process control circuit and are a decisive factor in efficient plant management. At Flowtec, every control valve is individually adapted to each process and control circuit and designed accordingly. Different control valves such as ball valves, ball segment or globe valves, butterfly valves, diaphragm valves and others are available for individual use and can be equipped with appropriate accessories such as an intelligent positioner. A wide range of actuators is also available.
Sicherheitsventile-Tosaca-DINxANSI-Niederdruckbereich
Safety valves
No pressure. No stress. For reliable protection of your property, plant parts and the environment. Our comprehensive range of pressure relief and safety valves is fully operational at all times and protects the system against damage caused by overpressure. As soon as the operating conditions have returned to normal, the system closes again. Tosaca's many years of experience in the design and manufacture of safety valves helps with any worst-case scenario.

Valves by application

We know every trick in the book.
Every industry has its own unique process requirements – or maybe not? Chemical resistance, high temperatures or abrasive media always pose similar challenges on industrial valves. As we operate in a wide range of industries, we can use our know-how so that we always provide the best solution for the particular requirement.

Paper applications
Our winning formula. For cost efficiency and planning certainty. The scope of paper applications is as diverse as the requirements placed on the production plants. In addition to a wide range of valves, customers also search valves with a large operating range providing flexible use. Avoid downtimes and waste! To achieve the product quality required in stock preparation, we rely on control and butterfly valves that regulate the compliance with the surface weights, offering the highest precision. We also know which valve is the right one for our customers in the area of pulp dewatering application, so as to avoid fibre bundles and therefore quality defects. Economical and robust! For wastepaper applications, design adjustments in reject handling ensure perfect functionality. Customers search wear-resistant models in special paper production, amongst others: Ceramic valves prolong the service life and cost-effective products ensure economic efficiency.
Zellstoff-Somas-Kugelventil-SKV-SKVT
Pulp applications
For low life cycle costs from wood chips to smooth fibres! Corrosion and abrasion suppress the resistance of valves, especially in pulp dewatering, and the digester. This has a negative impact on economic efficiency and operational safety. With a targeted selection of the design and material the area of digesters, washing, EDA and stock preparation, we make maintenance intervals calculable and prevent unplanned shutdowns.
Hochtemperatur-Herberholz-Drossel-Abdichtklappe-HRDxHRAx015-x018
High temperature
Tight and resistant – even if it’s getting hot. In steam applications (boilers, blast furnaces) or a wide range of gas applications, such as in regeneration phases, in the flare line area in refineries or in engine testing facilities, temperatures occur at a level that requires a special selection of valves. In order to guarantee leakage rates to suit customer requirements, through to complete tightness in the bore and to the outside, as well as to maintain the resistance and full functionality of the valve even at these high temperatures, materials such as high-temperature steel and special stainless steels are used. In addition, we also rely on special switching shafts and pack designs. We also take care to choose the right type of valve, which is selected according to process data and customer requirements as well as general requirements (such as certifications or material analyses).
Hochdruck-Energie-Wakmet-HochdruckAbsperrschieber-metallischdichtend
High pressure
For a long service life. High-pressure applications are found in most industries, but above all in the oil and gas industry, the petrochemical industry, in power plant construction and in the gas storage part of many processes. Contaminated media cause mechanical damage at high pressure and the resulting high flow rates. In addition, high leakage rates, high pressure drops and strong vibrations are problems that arise in high-pressure applications. The aim is to ensure good operability despite high differential pressures, to achieve the best possible leakage rates, to reduce the pressure in the valves and to achieve low wear and tear in order to increase the service life of the valves. It is important to select the correct type of valve as a first step. We also keep an eye on the best price-performance ratio in the course of our consulting. The service life is extended by high-quality materials that are chosen depending on the medium. To keep the leakage rate low, it is necessary to choose the correct version – soft or metal seated – or to generally choose linear or rotating valves.
Absperrklappen-Quadax-4-fach-exzentrische -Hochleistungsklappe-840x400-112
Low temperatures
Bring on the ice age. For full function despite ultra-low temperatures. Cryogenic or low temperature technology – with falling temperatures in the process, the risk of iced-up valves, blocked mechanisms and a lack of tightness increases. This applies in particular to processes with liquefied gases down to a temperature of minus 196°C, LNG (liquid natural gas) and media such as N2 (liquid nitrogen) in the pharmaceutical and food sector, O2 (oxygen) in the medical sector, liquid CO2 in food and industrial applications, as well as LAr (liquid argon) in welding applications, storage tanks, storage containers and transport lines. In order to fully maintain the functionality and operability of the valve in these applications and to ensure the lowest leakage rates in the bore and to the outside, we use special shafts and packing designs, for example.
Keramikkugelhahn-Cera-System
Abrasive media
Not only the hard ones get through. For greater operational reliability and failure reduction. Media such as TiO², limewater (plaster), CaCO3 (GCC), salts, sand, scale or comparable solids or process residues are reasons for rapid and strong mechanical wear. An inexpensive valve lined with elastomer or silicone or a pinch valve can already be the best solution. But sometimes the material resistance, installation situation, flow rate, pressure and temperature make adjustments necessary. The Flowtec experts then recommend suitable housing shapes with the lowest pressure drop, harder metallic materials (duplex, hardened material), ceramic coatings and those with HiCo (STELLITE³ reg.TM) and tungsten carbide or also fully lined components made of SSIC, Al²O³, ZrO², SiNI or ceramic.
ChemischeBeständigkeit-Chemvalve-PTFE
Chemical resistance
Unassailable! We ensure a relaxed life in an aggressive environment. Not only aggressive media such as chlorine, acids and alkalis cause strong chemical wear. Even media that only become aggressive through a reaction (isolation) are a challenge for the resistance. In these cases, dead space in particular increases the chemical wear. Corrosion doesn't stand a chance at Flowtec: The material and design of our valves can be adapted to the medium to ensure good resistance. In addition, dead space-free valves or corner valves can improve resistance.
Wasser-Orbinox-Schieber-EB-300x300
Water and waste water
For tightness and durability. The demands placed on valves in water applications are diverse. Absolute purity is required when handling drinking water in municipal water supply. At Flowtec, you will not only find the right valves, but also the corresponding certificates. In the area of fresh water supply in industrial water supply, valves are exposed to increased wear due to solid substances and contaminated media in the process and utility water. Corrosion and oxidation also play a role when it comes to the durability of valves in water applications, especially in salty water, such as in seawater desalination. Tightness is called for in all these applications, but especially when it comes to waste water in sewage treatment plants. To ensure durability, corrosion resistance and water purity, we rely on valves in high-quality materials such as Duplex or Superduplex. For example, our range of knife gate valves ensures tightness, reliably shutting off the flow in sewage treatment plants. The Hydromat is not deterred by mussel larvae; it closes the fresh water supply tightly at all times.
Wasserkraft-Erhard-Roco-wave
Hydropower
For safe operation. In the power plant and hydropower sectors, high pressure and hydraulic shocks must be taken into account in addition to the general requirements for water applications. The proper dimensioning of the valve helps to generate the optimum flow values. Needle valves or piston jet valves regulate the necessary pressure drop and our quick-release valves provide safety for emergency closures.
Dampf Energie-TTVColossus
Steam and energy
Full steam ahead. For economical and safe operation of all plants. Energy is provided in form of steam in almost all production areas and processes – whether in factories, the heat supply, energy production or in hospitals. Whether steam boilers, heating networks or steam applications: Production steam must be available at the right temperature. Damage to the installation due to an excessively high temperature and efficiency problems caused by a too low temperature should be avoided, as well as temperature fluctuations, which considerably reduce the service life of the boiler and turbine components. The use of multi-stage control valves reduces unwanted differential pressures. They stand for accuracy and reliability. Properly designed control valves prevent cavitation and flashing and ensure that wear is kept to a minimum. When using manual valves, higher-quality materials extend the service life of the valve.
Feststoffhaltig-RF-Schlauchquetschventil
Media containing solids
A consulting matter. For robust solutions and trouble-free operation. Bulk materials or sand in the mining sector, heavily contaminated media such as liquids or gases in the petrochemical industry, long or short-term media in the pulp and paper industry or general silo applications put the service life and functionality of valves to the test due to mechanical stress as well as jamming and blockages. The aim is to use a robust valve to suit the respective application. The choice of the right design is the first priority. In individual consultations, we find the right type with the right material. To ensure reliable closing despite the solid substances, or also to sustainably prevent materials from getting between the plate and the seal while opening and closing the valve, a special solution to suit the requirements and budget may also be advantageous. These range from pinch valves, special bulk material gate valves or special ball valve designs to the Junk Trap.
Pharma-PeterMeyer-Weichdichtend-vollverschweißt-totraumarm-Kugelhahn111-300x300
Pharmaceutical applications
Nothing but the highest quality. For chemical resistance and cavity-free processes. The pharmaceutical industry places the highest demands on production processes and plant components such as valves. In processes in the pharmaceutical industry, a sterile environment, purity in the process and no contamination are an absolute must. This is achieved in the valve sector by means of dead space and oil and grease-free valves. High-quality materials such as high-grade stainless steels or PTFE are used to ensure chemical resistance. Here we rely on valves from Chemvalve Schmid and Peter Meyer with the TEK ball valve. Where the highest product quality is required, control of the media plays a major role: The cavity-free sampling valves from Guichon provide safety.
