  • DSV® Sanitary Check Valves

    The DSV® 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. 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.

    The DFT® sanitary check valves meet 3-A Standard 58-02 and certified Clean in Place. Applications include pharmaceutical, chemical, beverage/beer, food, dairy industries and others.
