Soft seated, butterfly valve
Type GRW (Zwischenflansch) / GRL (Anflansch) (Emerson)
Pressure: 16bar (DN20-DN300) 10bar(DN350-DN900)
Nominal size: DN20-DN900
“The Emreson resilient seated butterfly valve is a centric butterfly valve with a split shaft (up to DN300), rounded polished disc edge, centring bores on the valve housing and an extended valve neck allows for pipe insulation.
The type GRW is designed as a wafer type valve and the GRL as a flanged type valve according to EN558 series 20, with a spheroidal cast iron housing and a disc in 1.4408 steel. “
Butterfly valve, low temperatur
Type VSS LT (Somas)
Pressure: 25
Nominal size: 80-500
“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.”
