“The Somas butterfly valve type VSS LT is designed for a wide range of liquids, gases and steam for temperatures down to -196°C (-320°F).
The valve can be designed as a control, on/off or manual valve.
The VSS LT valve can be supplied in a wafer and lugged design.
The valve has a triple eccentric valve design. The unique shape of the disc enables the use of a solid stainless steel seat. The solid seat remains unaffected by high flow velocities and provides good valve function, even in the most difficult applications.”
