Flow and Level Monitoring and Control

Compact Threaded On/Off Valves

Install these low-profile valves in tight spots. Use with water, oil, air, and inert gas.

On/Off Valves with Barbed Fittings

Metal provides more durability than plastic. These valves have barbed fittings that grip onto tubing for a secure hold. Use them with water and air.

Plastic On/Off Valves with Barbed Fittings

Plastic provides a lightweight and economical alternative to metal. All valves have barbs that grip onto tubing for a secure hold. They’re for use with water, oil, air, and inert gas.

On/Off 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. Use these valves with water and oil.

On/Off Valves with Barbed Fittings for Chemicals

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.

Compact Threaded On/Off Valves for Chemicals

For chemical-processing applications in confined areas, these valves have an EPDM seal and a PVC or CPVC body to withstand aggressive and corrosive solutions and a low-profile handle to fit in tight spots.

Sampling Valves for Fuel

Often installed on petroleum loading arms to test fuel quality without interrupting flow, these valves are fire-tested to meet American Petroleum Institute (API) 607, Edition 5, for securely isolating fluid and preventing the spread of fire.

Drainage Valves

Also known as stop cocks, install these valves on your tank for easy draining.

Easy-Grip Drainage Valves

The large knob makes these drainage valves easy to grip.
