    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.

    High-Cycling Threaded Check Valves

    With few moving parts to wear out, these valves withstand frequent opening and closing, pulsating flow, and rapid flow reversal. 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.

    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.
