“The Somas butterfly valve type VSS LN is a low-noise control valve with a metal seat. With the “”low-noise” noise-reducing device, flashing and cavitation problems can be eliminated and low noise levels can be achieved.
The wafer valve is designed for a wide range of liquids, gases and steam at temperatures up to 550°C.

Die Doppelexzentrische Hochleistungs-Absperrklappe bietet eine dichte Absperrlösung für die anspruchsvollsten Anwendungen.
Weitere Varianten im Programm: Konzentrische, doppelt exzentrische und dreifach exzentrische Ausführung.
The throttle valves RD and RA are designed as a wafer type valve with a centric valve disc and are suitable for operating temperatures up to 800°C, depending on the choice of material.
For flanges according to DIN EN 1092-1 or ASME B16.5 / ASME B16.47. Lengths according to the company standard.
Connecting flange for actuators to DIN EN ISO 5211.
Testing according to DIN EN 12266.
Versions:
RD without seat (leakage approx. 1% of surface equivalent),
RA with metal travel stop ring (leakage approx. 0.5% of surface equivalent),
RA with seal ring (leakage approx. 0.3% of surface equivalent),
RA with metal travel stop ring with seal ring (leakage approx. 0.1% of surface equivalent)
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.
