Also known as whistle valves, these open and throttle as force is applied to the lever and automatically close upon release. They’re commonly used for spraying, washing, and other applications that require manual discharge of liquid and air. Use with water, oil, air, and inert gas.

Also known as proportional V-ball valves, these have a motor that adjusts and regulates flow in applications with higher flow rates and pressures than solenoid valves. As you increase the intensity of the electrical signal, the motor opens the valve, moving a ball with a V-cut opening that proportionately allows more flow as the valve opens. They're often integrated into PLC systems for automatic control over the valve position based on system conditions.

Often attached to differential pressure gauges to measure liquid level in tanks, these manifolds have two isolation valves with a pressure-equalizing valve between them. To isolate your differential pressure gauge for maintenance or calibration, shut off flow on both sides and equalize pressure in the manifold. They are rated for at least 6,000 psi. Use with water, oil, air, and inert gas.

Also known as block and bleed valves, these have two vent ports to isolate pressure gauges, switches, and other components in high-pressure systems for maintenance, calibration, and sampling without interrupting the process. They are rated for up to 10,000 psi. Use 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.

With a gauge port on each side of these valves, you can install two different pieces of instrumentation equipment to simultaneously monitor multiple media properties without interrupting flow. Use 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.

Rated for nearly twice the maximum temperature of standard threaded precision flow-adjustment valves, these can handle up to 700° F. They’re for use 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.

For installation in instrument panels, these valves have a hex nut and threads below the handle. Use 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.

The color-coded threads and numerical markings on these valves ensure consistent and repeatable settings. One full revolution of the handle reveals a new color to indicate the set point. Use 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.

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.

With a low-profile body and a narrow port-to-port length, these valves fit in tight spots. Barbs grip onto tubing, providing a secure hold. These valves are for use 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.

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.
