About Precision Flow-Adjustment Valves

Compact Threaded On/Off Valves for Fuel

A low-profile handle allows these valves to fit in low-clearance pipelines for diesel fuel, fuel oil, gasoline, and kerosene.

On/Off Valves with Compression Fittings

For more durability than plastic valves, these are made of metal. A compression sleeve bites into tubing as you tighten the nut, forming a strong seal. Use these valves with water, oil, air, inert gas, and steam.

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 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.

Precision Flow-Adjustment Valves
with 45° Flared Compression Fittings

With 45° flared tube fittings, these valves form a tight seal on metal tubing. Use with air. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment
Valves with Compression Fittings

A compression sleeve bites into tubing as you tighten the nut, forming a strong seal. These valves are for use with air. 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.

Threaded Precision Flow-Adjustment Valves for Fuel

Valves have NPT connections for use with threaded pipe. Turn the handle to adjust the flow of butane, diesel fuel, fuel oil, gasoline, kerosene, natural gas, and propane in small increments.

Precision Flow-Adjustment Valves
with Barbed Fittings for Fuel

Add fine flow control to tubing lines for oil, butane, diesel fuel, fuel oil, gasoline, kerosene, natural gas, and propane. These valves have a barbed fitting that grips onto tubing, providing a secure hold. Turn the handle to adjust flow in small increments.

Multiport Threaded Diverting Valves

Divert the flow of compressed air and other media to multiple pieces of equipment. Use with water, oil, air, and inert gas.

Electric-, Air-, and Hydraulic-Powered Motion Control

Inline Air Flow Control Valves with Flow Indicator

Designed to be mounted inline, these valves can be placed in an easy-to-reach location along your line to control the speed of air-powered equipment by adjusting the volume of airflow. A numeric indicator provides a relative measure of airflow, similar to the volume dial on a speaker, so it's easy to set the same flow rate with each use.

Elbow 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. They control the speed of air-powered equipment by adjusting the volume of airflow.

Inline Air Flow Control Valves

Designed to be mounted inline, these valves can be installed in an easy-to-reach location along your line. They control the speed of air-powered equipment by adjusting the volume of airflow.

High-Pressure Air Flow Control Valves

These valves handle pressure up to 265 psi. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

Air-Exhaust Flow Control Valves

Install these valves in the exhaust ports of air directional control valves to control exhaust air speed without needing access to your cylinder.

Flow-Adjustment Inline Hydraulic Valves

Adjust the flow rate as needed.
