Double eccentric butterfly valve
The double eccentric butterfly valve ROCO wave is designed for water applications.
The valve is characterised by high energy efficiency, a flow-optimised design, minimal pressure losses and continuous corrosion protection.
The connection between the shaft and valve disc is covered by a polygon connection.
The double eccentric butterfly valve has a modular actuator concept through the use of a handwheel, electric actuator, stem extension, weight-loaded hydraulic actuator, pneumatic actuator or chainwheel.

Double gate knife gate valve
“The knife gate valve type DT from Orbinox is a bi-directional gate valve that is mainly used for higher consistencies in the pulp and paper industry (paper recycling), but is particularly used for heavily contaminated fibrous media.
Closing and opening times are only half as long as with other gate valves.
All parts that are subject to wear can be easily replaced.”
Fixed cone valve
“The Orbinox fixed cone valve type CH is a special round valve for the shut-off or control of water in dams, pumping processes and in hydropower plants.
The gate valve in a sturdy welded design is available in many design options depending on the dimensions, operating pressure or required material. “
Low noise ball segment valve
Somas ball segment valves type KVTW LN (KVTF LN) with a centrically mounted shaft and KVXW LN (KVXF LN) with an eccentrically mounted shaft were developed to reduce noise levels.
The reduction in the noise level is achieved by the installation of a noise-reducing device. The noise-reducing device is mounted behind the ball segment and consists of several steel rods in a specific arrangement. These steel rods distribute the pressure drop over several stages. This reduces the noise level and prevents any cavitation.
The KVTW LN and KVXW LN are supplied as wafer type valves and the KVTF LN and KVXF LN as flange type valves.
Metal seated butterfly valve
“The Somas metal seated butterfly / shut-off and control valve type VSS is suitable for controlling and shutting off liquids, steam and gases over a wide temperature range.
The triple eccentric design allows the use of a solid stainless steel seat due to the special contour of the disc. The disc geometry and the shape of the seat provide excellent tightness.
The seat is resistant to high flow velocities and ensures good tightness, even under difficult operating conditions. The seat, which is available in different materials, can be replaced.
The VSS valve was developed as a wafer valve and can also be supplied as a lug type valve (with threaded bores).”
