Check Valves with Sanitary Quick-Clamp Fittings for Food and Beverage
- For Use With: Beverage, Food
- Piston Material: 316 Stainless Steel
- Spring Material: 316 Stainless Steel
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) 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.
Replacement seals include both of the seals you need for a leak-proof valve.

Vacuum-Breaking Valves for Chemicals
A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals. Also known as vacuum breakers, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.
