Bellows Seal Valves

Mon, 08/20/2012 - 1:00am

Single and double bellows Clampseal® valves allow for zero emissions and are ideal for applications where packed valves may not reliably contain light gases or hazardous system fluids due to leakage in the stem/packing seal area or stuffing box wall/packing seal area. The units meet all requirements of MSS SP-117 and are available in 1/2" through 4" sizes in Y, T and angle configurations through ASME/ANSI Class 2500. Standard materials include carbon steel SA105; chrome-moly SA182-F22, F91; and stainless steel SA182-F316, FM16L and F347. Options include electric, pneumatic and hydraulic actuators; open, closed or both locking devices; single or dual limit switches; position indicator; and leak-off port.
