    Check Valves for Refrigerant

    Use these valves in refrigeration and air-conditioning systems. All open to allow flow in one direction and close when flow stops or reverses. They solder to copper tubing for a permanent, leak-tight connection.

    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.
