High-Flow Threaded Check Valves

To achieve the maximum possible flow, internal components are designed to reduce flow resistance. These valves open to allow flow in one direction and close when flow stops or reverses. A removable cap provides easy access to internal components for maintenance.

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.

Repair Kits—Repair kits include everything you need to rebuild the valve.

Check Valves with Solder-Socket Fittings

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.

Vacuum Breakers

Also known as vacuum-breaking valves, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.

Straight

Straights are often used with steam coils, heat exchangers, and space heaters.

Heavy Duty Check Valves with Push-to-Connect Fittings for Drinking Water

A metal body provides more durability than plastic. Insert tubing into the push-to-connect fittings—no heat, solder, or flux required. These valves meet NSF/ANSI 61 for use in drinking water systems. They open to allow flow in one direction and close when flow stops or reverses.
