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.
“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).”
