To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings. The plastic body and fluoroelastomer seal provide excellent chemical resistance. Valves open to allow flow in one direction and close when flow stops or reverses.
Valves for drinking water meet NSF/ANSI 61.
PVC and CPVC valves come with unthreaded socket-connect female fittings in addition to the threaded NPT female fittings.
Polypropylene valves are more corrosion resistant than PVC or CPVC valves.
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.

To reduce installation time and allow for maintenance without detaching pipe connections, these valves insert into a union fitting. Union fittings are sold separately. Valves open to allow flow in one direction and close when flow stops or reverses. Body is 316 stainless steel for excellent corrosion resistance.
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.

Keep backflow from contaminating your drinking water supply—these valves meet NSF/ANSI 61 for use with drinking water. They consist of a primary check valve and a secondary check valve. If the primary check fails to close when flow stops or reverses, the secondary check valve engages to prevent backflow.
Single-union valves have a union fitting on one end.
Double-union valves have a union fitting on both ends.
