Check Valves with Sanitary Quick-Clamp Fittings for Food and Beverage

To maintain sanitary standards in food, beverage, and dairy applications, these valves have sanitary quick-clamp connections and polished internal surfaces for easy cleaning. They open to allow flow in one direction and close when flow stops or reverses. All have a 316 stainless steel body for excellent corrosion resistance.

Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
