DFT DSV Sanitary Check Valves

The DFT DSV Sanitary Check Valve is an in-line spring-assisted check valve designed to prevent flow reversal in industries with strict cleanliness codes. To accommodate various piping arrangements, the DSV is available as a "Vertical" or "Horizontal" valve, in sizes ranging from 1/2" to 4". The Horizontal valve is for Horizontal lines requiring a self-draining valve. The "Vertical" design is for "Vertical" installations and "Horizontal" lines when a self-draining valve is not required. The DSV, with a 316L stainless steel body and seat, is fastened with a quick release clamp and elastomeric body seal to permit fast and easy access to the internals. The disc and seat are lapped to provide excellent shutoff.
