For use with threaded pipe, these valves are available with NPT, NPTF, BSPP, BSPT, and UNI/UNF (JIC) connections.

To achieve the maximum possible flow, internal components are designed to reduce flow resistance.

Plastic provides a lightweight alternative to metal.

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

Barbs grip onto tubing, providing a secure hold.

Two sleeves give the fittings extra gripping power. They bite into tubing as you tighten the nut to form a strong seal. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Less than half the end-to-end length of standard flange-mount check valves, these can be installed in pipelines with limited clearance.

Insert tubing into the fitting—no heat, solder, or flux required.

Weld to unthreaded metal pipe.

Also known as backwater valves, these valves prevent backflow of sewage and wastewater in drain, waste, and vent systems.

Weld these valves to unthreaded pipe for a smooth, flush connection that provides maximum flow.

These valves open to allow flow in one direction and close when flow stops or reverses.

The most chemical-resistant check valves in our offering, these have a PFA body to withstand methyl ethyl ketone, sodium hypochlorite, and other extremely harsh chemicals.

Insert tubing into the fittings—no heat, solder, or flux required.

Visually inspect flow and debris accumulation through the transparent valve body.

For more than twice the temperature rating of standard check valves for oil and fuel, these have a heat-resistant fluoroelastomer seal that can withstand temperatures up to 500° F.

Rated for at least four times the pressure of standard check valves for oil and fuel, these are often used in hydraulic applications with pressures up to 3,000 psi.

For more durability than plastic, these valves have a metal body.

Valves have a plastic body.

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection.

To maintain sanitary standards in food, beverage, and dairy applications, these valves have sanitary quick-clamp connections and polished internal surfaces for easy cleaning.

Valves have NPT connections for use with threaded pipe.

Commonly used with irrigation systems and laboratory equipment, these valves have NPT connections.

Prevent dirty, contaminated water from backing up into your garden hose line—install these valves between a faucet and a garden hose.

Attach these valves with NPT connections to threaded pipe.

These valves open to allow flow in one direction and close when flow stops or reverses direction.

Release pressure in the line between a compressor and an air storage tank, making start-up easier on the motor. These valves open to allow flow into the tank and close when flow stops or reverses direction, preventing air from escaping the tank when the air compressor is not running.

Also known as dry disconnects and double shut-off couplings, these have a shut-off valve in the plug and socket for minimal fluid loss when disconnecting the hose line.
