Check Valves for Refrigerant
- For Use With: Refrigerant
- Ball Material: Stainless Steel
- Spring Material: Stainless Steel
- Seal Material: Neoprene Rubber
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) 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.
