On/Off Valves for Fuel

Threaded On/Off Valves for Fuel

Protect personnel and equipment in the presence of diesel fuel, fuel oil, gasoline, and kerosene. Fire-tested to meet American Petroleum Institute (API) 607, Edition 4, these valves are designed to securely isolate fluid and prevent the spread of fire.

On/Off Valves with Yor-Lok Fittings for Fuel

For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Use with diesel fuel, fuel oil, gasoline, and kerosene.

Backflow-Prevention Valves

Check Valves with Solder-Connect
Fittings for Drinking Water

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

Heavy Duty Threaded Check Valves for Drinking Water

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

Threaded Check Valves for Drinking Water

Body is plastic.

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

Valves have a plastic body.

Flange-Mount Check Valves for Drinking Water

Sandwich these valves between ANSI flanges.

Socket-Connect Check Valves for Drinking Water

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection.

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

The metal body is more durable than plastic.

Flanged Check Valves

Bolt to ANSI flanges.

Flange-Mount Check Valves

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.

Butt-Weld Check Valves

Weld these valves to unthreaded pipe for a smooth, flush connection that provides maximum flow.

Compact Flange-Mount Check Valves

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

Flanged Check Valves for Harsh Chemicals

Bolt to ANSI flanges.

Threaded Check Valves for Harsh Chemicals

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

Easy-to-Install Threaded Check
Valves for Harsh Chemicals

To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings.

Flange-Mount Check Valves for Oil and Fuel

Install these valves between ANSI flanges.

Threaded Two-Stage Backflow-Prevention
Valves for Drinking Water

Easy-Maintenance Threaded Two-Stage
Backflow-Prevention Valves for Drinking Water

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

Vacuum-Breaking Valves with Garden-Hose Fittings

Prevent dirty, contaminated water from backing up into your garden hose line—install these valves between a faucet and a garden hose.

Vacuum-Breaking Valves for Chemicals

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