Cylinder Valves SSWN-22/V-S for Ammonia & Amines - Stainless Steel

Handwheel operated Stainless Steel Cylinder Valve for Ammonia and Amines in Stainless steel body in SSWN-22/V-S3 design.

The design has two-piece spindle and uses compressed packing backed by O-ring sealing technology to provide reliable operation during the entire service life while ensuring low torque operation and freedom from gland leakage in service.

The design also prevents gas contamination as there is no lubrication and threaded parts in the gas wetted area.

The design series is offered in PCTFE/PA 66 seating and choice of EPDM/FKM O-ring depending upon gas application and is suitable for maximum test pressure of 250 bar.
