Flow-Control Valves

Premium Solenoid On/Off Valves

These top-of-the-line valves are comparable to Asco Red Hat 8210G Series and Parker Gold Ring 23C Series.

Premium Compact Solenoid On/Off Valves

Comparable to Asco Red Hat 8210G Series and Parker Gold Ring 23C Series, these valves meet the highest quality standards.

On/Off Valves with Yor-Lok Fittings

For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves are for use with water, oil, air, and inert gas.

Panel-Mount On/Off Valves with Yor-Lok Fittings

Threads and a hex nut below the handle allow you to install these valves in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Use these valves with water, oil, air, inert gas, and steam.

Fast-Acting Panel-Mount On/Off
Valves with Yor-Lok Fittings

Flip the toggle to quickly turn these valves on and off. All have threads and a hex nut below the handle for installation in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves are for use with water, oil, air, and inert gas.

On/Off Valves with Yor-Lok Fittings for Chemicals

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. All have a PTFE seal and a corrosion-resistant 316 stainless steel body that can stand up to aggressive and corrosive solutions in chemical-processing applications.

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.

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.

Precision Flow-Adjustment Valves with Yor-Lok Fittings

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. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Use these valves with water, oil, air, and inert gas. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves
with Yor-Lok Fittings for Chemicals

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. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. The 316 stainless steel body and seal, the PTFE seat and packing, and the Monel needle can withstand aggressive and corrosive solutions in chemical-processing applications. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves
with Yor-Lok Fittings for Steam

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. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Diverting Valves with Yor-Lok Fittings

These valves divert flow between ports. Use with water, oil, air, and inert gas.
