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

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

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

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

Barbs grip onto tubing, providing a secure hold.

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.

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.

With internal components that resist wear from frequent operation, these valves can cycle as often as once per second.

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

Insert tubing into the fitting—no heat, solder, or flux required.

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.

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.

Insert tubing into the fittings—no heat, solder, or flux required.

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

Sandwich these valves between ANSI flanges.

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.

Install these valves between ANSI flanges.

To withstand high pressures and temperatures in steam service applications, these valves have a 316 stainless steel body, PTFE ball, and PTFE seal.

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.

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.

Attach these valves with NPT connections to threaded pipe.

Replace worn or broken parts on your transfer pump.

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

Release pressure in the line between a compressor and an air storage tank, making start-up easier on the motor. These valves open to allow flow into the tank and close when flow stops or reverses direction, preventing air from escaping the tank when the air compressor is not running.

Air pressure must be supplied to both inlets before the output port will open, allowing air flow to downstream components. Also known as "and" valves.

Protect air-powered equipment in emergency shut-off situations—when system pressure drops, these valves automatically close to stop cylinder motion, even at mid-stroke. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

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

Stop the reverse flow of gas in your torch.

440A stainless steel resists damage from impact and abrasion. It's often used for cutlery and valve components.

Clean screens in vibrating sifters with the bounce of these balls, or use them as seals in pumps and check valves.

Known for its naturally slippery surface, PTFE surpasses most plastics when it comes to chemical resistance and performance in extreme temperatures.

Use these balls as seals in pumps and check valves, or let them bounce inside of vibrating sifters as an effective screen cleaner.

FDA compliant for direct contact with food, these balls are often used to clean screens in vibrating sifters in food, beverage, and other sanitary environments. You can also use them as seals in pumps and check valves.

Practically nonabsorbent, HDPE won't swell when exposed to moisture. It is denser and more rigid than LDPE, plus it's more chemical resistant.

Build a custom 1/4" system to deliver coolant, cutting oil, water, or air in any direction.

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