About Precision Flow-Adjustment Valves

Easy-Set Threaded Precision Flow-Adjustment Valves

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.

Threaded Precision Flow-Adjustment Valves

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.

High-Pressure Threaded
Precision Flow-Adjustment Valves

Often used in hydraulic and compressed air systems, these valves can withstand at least 6,000 psi. 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.

Panel-Mount High-Pressure Threaded
Precision Flow-Adjustment Valves

Designed for high-pressure instrumentation applications, these valves are rated for up to 10,000 psi and have a hex nut and threads below the handle for panel mounting. 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.

High-Pressure Threaded Precision
Flow-Adjustment Valves with Vent Ports

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.

High-Pressure Threaded Precision
Flow-Adjustment Manifolds

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.

Panel-Mount Threaded Precision
Flow-Adjustment Valves

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.

High-Precision Threaded Flow-Adjustment Valves

To ensure highly precise flow adjustment, these valves adjust flow in smaller increments than other valves for finer control over the flow rate in metering and sampling applications. Use them with water, oil, air, and inert gas.

High-Temperature Threaded
Precision Flow-Adjustment Valves

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.

Threaded Precision Flow-Adjustment
Valves with Gauge Ports

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.

Threaded Precision Flow-Adjustment
Valves with Vent Port

Also known as block and bleed valves, these have a vent port that allows you to remove instrumentation equipment attached to the valve without depressurizing your line. Turn the handle to shut off flow and remove the vent port plug to drain liquid trapped in the valve. Use them with water, oil, air, and inert gas. These valves adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

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.

Compact Precision Flow-Adjustment
Valves with Barbed Fittings

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.

Precision Flow-Adjustment Valves
with Solder-Connect Fittings

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

High-Pressure Threaded Precision
Flow-Adjustment Valves for Steam

To withstand a maximum steam pressure of at least 4,800 psi @ 355° F in applications such as petroleum refineries, these valves are machined from a single piece of metal for seamless construction. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves with
Sanitary Quick-Clamp Fittings for Clean Steam

Often used in sterilization applications with clean steam, these valves are electropolished to a 16 Ra finish for smooth internal surfaces that prevent product buildup and inhibit bacteria growth.

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.

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.

Elbow Corrosion-Resistant Air Flow Control Valves

Mount these valves directly to cylinder ports, eliminating additional tubing between the cylinder and valve for better control than inline valves. Made of plastic and stainless steel parts, they have excellent corrosion resistance. They control the speed of air-powered equipment by adjusting the volume of airflow.

Metering Valves for Abrasive Blasting

Control the amount of abrasive material that your blast hose releases by using these valves, which have a knob for adjusting the size of their opening.
