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.

At 1 1/2" long or less, these valves fit in confined spaces.

The heat-resistant rubber seal withstands temperatures up to 500° F.

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.

Sandwich these valves between two ANSI flanges for backflow prevention at a fraction of the weight of flanged check valves and a reduced pipeline footprint.

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.

To reduce installation time and allow for maintenance without detaching pipe connections, these valves insert into a union fitting.

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.

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.

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

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.

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

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.

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

Stop backward flow in outdoor faucets with garden hose thread (GHT) outlets.

These arresters attach directly to torches that cut steel up to 8" thick.

Stop the reverse flow of gas in your regulator.
