Heavy Duty Check Valve with Barbed Fittings

For more durability than plastic barbed check valves, these have a stainless steel body. Barbs grip onto tubing, providing a secure hold. Valves open to allow flow in one direction and close when flow stops or reverses. The stainless steel body provides excellent corrosion resistance. Great for those who are concerned about condensation in the bucket's vacuum line.

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.
