Description
The Spirax Sarco DCV3/B boiler feed check valve is designed specifically for use on boiler feedwater 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. Face-to-face dimensions conform to EN 558 part 1, series 49.
Note: The Spirax Sarco DCV3HE is similar in specification and
appearance, but has a slightly different seat design. We only
recommend the DCV3/B for boiler feedwater applications.
