With a shorter end-to-end length than other check valves, these fit in tight spaces.

Plastic provides a lightweight alternative to metal.

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

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

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

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

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.

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

Bolt to ANSI flanges.

Also known as luer lock couplings, quick-turn fittings consist of a plug and a socket that connect with a half turn, so you can easily connect and disconnect your line.

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.

Barbs grip onto tubing, providing a secure hold.

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

Bolt to ANSI flanges.

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

Valves have a plastic body.

Sandwich these valves between 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.

Install these valves between ANSI flanges.

Barbs grip onto tubing, providing a secure hold.

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.

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

A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals.

Solder these valves to copper tubing for a permanent, leak-tight connection.

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

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

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.

Stop the reverse flow of gas in your torch.

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

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.
