For use with threaded pipe, these valves are available with NPT, NPTF, BSPP, BSPT, and UNI/UNF (JIC) connections.
The heat-resistant rubber seal withstands temperatures up to 500° F.
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.
Plastic provides a lightweight alternative to metal.
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 these valves to unthreaded pipe for a smooth, flush connection that provides maximum flow.
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.
For more durability than plastic barbed check valves, these have a stainless steel body.
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.
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.
The metal body is more durable than plastic.
Valves have a plastic body.
Solder to copper tubing for a permanent, leak-tight connection.
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.
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.
Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.
Insert tubing into the fittings—no heat, solder, or flux required.
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.
These valves open to allow flow in one direction and close when flow stops or reverses.
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.
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.
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.
A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals.
Also known as check valves, these open to allow flow in one direction and close when flow stops or reverses.
