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

Rated for up to twice the pressure of standard check valves, these can withstand pressures up to 3,000 psi.

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

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.

Barbs grip onto tubing, providing a secure hold.

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

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.

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

Bolt to ANSI flanges.

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.

Plastic provides a lightweight alternative to metal.

These compact valves fit into standard sanitary quick-clamp fittings. All are FDA Compliant 21 CFR 177.2600 and have polished surfaces for easy cleaning.

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

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

The metal body is more durable than plastic.
