Single and Double Bellows Valves
Conval offers a complete line of single and double bellows Clampseal® valves. These 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.
Clampseal bellows seal valves 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; stainless steel SA182-F316, F316L 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.
