    Check Valves with Barbed Fittings

    Barbs grip onto tubing, providing a secure hold. These valves open to allow flow in one direction and close when flow stops or reverses.
    Nylon Body—Spring-Loaded Ball
    Nylon valves are more impact resistant than PVC or polypropylene valves.
    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.
