DCV3B Disc Check Valves

SPIRAX DISC WAFER PATTERN NON RETURN VALVE

The Spirax Sarco DCV3/B boiler feed check valve is designed specifically for use on boiler feed-water systems. It is a stainless steel disc check valve with a soft EPDM seat to ensure tight shut-off against boiler pressure, even under poor water conditions. The DCV3/B is normally installed between flanges in the boiler feed water line. Cast-in lugs on the valve body allow the valve to be centralised easily.

Austenitic stainless steel body c/w EPDM seat and 10 PSI spring suitable for boiler water feed application.
