    Easy-Install Threaded Check Valves for Harsh Chemicals

    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.

    PVC and CPVC valves come with unthreaded socket-connect female fittings in addition to the threaded NPT female fittings.
    For Drinking Water—Valves for drinking water meet NSF/ANSI 61.
    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.

    Socket-Connect Check Valves for Harsh Chemicals

    Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection. These valves have a plastic body and a fluoroelastomer seal for excellent chemical resistance. They open to allow flow in one direction and close when flow stops or reverses.

    Vacuum Breakers for Chemicals

    A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals. 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.
