For use with threaded pipe, these valves are available with NPT, NPTF, BSPP, BSPT, and UNI/UNF (JIC) connections.
With a shorter end-to-end length than other check valves, these fit in tight spaces.
Rated for up to twice the pressure of standard check valves, these can withstand pressures up to 3,000 psi.
The heat-resistant rubber seal withstands temperatures up to 500° F.
At 1 1/2" long or less, these valves fit in confined spaces.
Plastic provides a lightweight alternative to metal.
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.
Insert tubing into the fitting—no heat, solder, or flux required.
Less than half the end-to-end length of standard flange-mount check valves, these can be installed in pipelines with limited clearance.
Barbs grip onto tubing, providing a secure hold.
For more durability than plastic barbed check valves, these have a stainless steel body.
Visually inspect flow and debris accumulation through the transparent valve body.
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.
Insert tubing into the fittings—no heat, solder, or flux required.
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.
To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings.
Bolt to ANSI flanges.
These heavy duty valves can withstand pressures up to 1,975 psi and temperatures up to 800° F.
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.
Insert unthreaded pipe into the socket ends and weld 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.
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.
Valves have NPT connections for use with threaded pipe.
For more durability than plastic, these valves have a metal body.
Body is plastic.
Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection.
Solder to copper tubing for a permanent, leak-tight connection.
The metal body is more durable than plastic.
Valves have a plastic body.
To withstand high pressures and temperatures in steam service applications, these valves have a 316 stainless steel body, PTFE ball, and PTFE seal.
These valves are often used in refrigeration and air-conditioning systems.
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.
Prevent air from escaping an air storage tank when the air compressor is not running. These valves open to allow flow into the tank and close when flow stops or reverses direction.
