About Backflow-Prevention Valves

Check Valves with Push-to-Connect Fittings

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

Check Valves with Barbed Fittings

Barbs grip onto tubing, providing a secure hold.

Heavy Duty Check Valves with Barbed Fittings

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

Check Valves with Yor-Lok Fittings

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.

High-Cycling Check Valves

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

Check Valves with Quick-Turn Fittings

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.

Check Valves with Solder-Connect Fittings

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

Check Valves with Barbed Fittings for Harsh Chemicals

Barbs grip onto tubing, providing a secure hold.

Check Valves with Push-to-Connect
Fittings for Harsh Chemicals

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

Check Valves with Push-to-Connect
Fittings for Drinking Water

Valves have a plastic body.

Check Valves with Barbed Fittings for Vacuum

Barbs grip onto tubing, providing a secure hold.

Check Valves with Sanitary Quick-Clamp
Fittings for Food and Beverage

To maintain sanitary standards in food, beverage, and dairy applications, these valves have sanitary quick-clamp connections and polished internal surfaces for easy cleaning.

Vacuum-Breaking Valves

Commonly used with irrigation systems and laboratory equipment, these valves have NPT connections.

Air Flow Check Valves

These valves open to allow flow in one direction and close when flow stops or reverses direction.
