- For Use With: Steam, Water
- Disc Material: Bronze
- Seal Material: Bronze
Solder these valves to copper tubing for a permanent, leak-tight connection. They open to allow flow in one direction and close when flow stops or reverses. All have a removable cap that provides easy access to internal components for maintenance.
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.
For technical drawings and 3-D models, click on a part number.
