For use with threaded pipe, these valves are available with NPT, NPTF, BSPP, and UNF connections.

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

To fit in confined spaces, these valves are less than half the length of other plastic valves.

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

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

Weld to unthreaded metal pipe.

For more durability than plastic barbed check valves, these have a stainless steel body.

Bolt to ANSI flanges.

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.

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

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

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 reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings.

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.

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

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

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.

These heavy duty valves can withstand pressures up to 1,975 psi and temperatures up to 800° F.

Valves have NPT connections for use with threaded pipe.

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

Integral shutoff valves isolate flow for inline maintenance, and a top-entry cover provides easy access to internal components.

Attach these valves with NPT connections to threaded pipe.

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

Rated for 12 times the pressure of standard vacuum-breaking valves, these can handle up to 1,500 psi. Connections are NPT.

Also known as check valves, these open to allow flow in one direction and close when flow stops or reverses.

Put an end to water damage from backed-up sewers. When water backs up, the rubber float will rise to seal off the drain. When water recedes, the float will drop for normal drainage.

Attach these arresters to the outlet connection of a regulator on a torch that cuts steel up to 11" thick.

Stop the reverse flow of gas in your torch.
