A large selection of materials makes the soft seated, floating DIN flanged ball valve flexible to use. With a wide range of approvals (Fire Safe, Fugitive Emission, ATEX, TRCU, CRN, SIL 3, and many others), it can be used in virtually all industries. "

Ball check valve

The Erhard ball check valve offers backflow protection based on the ball check valve operating principle. In the open position, the sealing ball is pushed out of the flow cross-section by the medium. The Erhard ball check valves are particularly suitable for use in the waste water sector where there is a high risk of clogging. Advantages: Erhard ball check valves are resistant to dirt and are extremely maintenance-friendly as the valve works without mechanically moving parts. In addition, the ball check valve has low flow resistance in the open position.

PTFE lined butterfly valve

The ChemValve-Schmid butterfly valve CST is the world's leading modular PTFE lined butterfly valve. The PTFE lined valve is produced to the highest quality standards for the safe handling of aggressive media. It is designed for the use with highly chemical media and is therefore used in almost all industries. Spherical structural elements reduce friction and therefore increase the service life.

You can
rest assured.

In addition to explosion safety, chemical media also place special demands on chemical resistance. Valves lined with PTFE or ceramic protect against particularly aggressive chemical media. Special materials, such as Duplex, Superduplex or Hastelloy©, withstand the greatest chemical attacks.

In the petrochemical industry in particular, hot heated media place particular demands on the proper functioning of plants on a sustainable basis. Our cavity free valves prevent the valves from stucking so that the system runs continuously without any problems.

Of course, our product portfolio also offers valves for all other requirements, such as high or low temperature. With highly viscous media, not only the high temperature is a criterion, but the butterfly valves have to grip harder to close reliably. We have corresponding products available in our range for this and for all gaseous media, for example with a PET, PE or PU coating.

At Flowtec, we know about the process requirements of petrochemical production. The best known companies in the petroleum and chemical industries rely on our valves.

Nothing
remains hidden.

Media used especially in the petrochemical industry, such as diesel, benzene or kerosene, are very expensive to produce. During a product changeover, for example in tank farms, valves should be completely emptied and ensure that all media remain where they belong, namely in the process. Here too, we have the right solution to transport this media without any losses and without mixing them.

For special tasks we have niche suppliers in our network who specialise in the chemical and petroleum sectors.

Everything is possible.

A special length or special flange connection? Not a problem, we adapt standard products in such a way that they fit perfectly into our customer's system. For specific problems, we develop customer-specific solutions with our partners.

Gate valves are tried and tested and good,
but are they good enough?

Have you ever thought about why you use classic gate valves or ball valves for certain steam, gas, low or high temperature applications? At Flowtec, we have scrutinised their use and evaluated whether it is possible to solve this in a different and better way: Yes, you can!

The use of our Quadax® four offset eccentric butterfly valve is an innovative solution that not only withstands extreme requirements. It is much more compact, smaller at a lower weight. At the same time, the Quadax® four offset eccentric butterfly valve offers a high tightness and is also easier to automate.

Control Seal Double Block and Bleed Valve

Best Practice

A valve solution
that will help you take off safely

An intelligent and efficient refuelling system requires an equally efficient and safe valve solution. We were able to deliver this at one of the most state-of-the-art airports in the German-speaking region with underground refuelling.

The kerosene is pumped through underground lines from a nearby tank farm directly to the aircraft holding bays. The aircraft are refuelled by airfield tanker vehicles without their own tank (dispenser or hydrant truck) through a refuelling pipeline in an underground pipe system.

Absolute safety in the form of 100% tightness has been ensured by a double block and bleed valve. Automatic emptying of the cavity ensures that no aircraft fuel is wasted.
