Clampseal single and double bellows seal valves from Conval 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. The valves come with a two-year warranty.
