About Flow Control Valves

Also known as cylinder speed controls, flow control valves let you control the extension or retraction speed of your air cylinder. They regulate airflow as it passes from the valve's inlet to its outlet. Air flows freely in the opposite direction.

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.

Flexible-Mount Air Flow Control Valves

A swiveling outlet port on these valves makes connections from any direction. They control the speed of air-powered equipment by adjusting the volume of airflow.

Precision-Adjust Air Flow Control Valves

A fine-adjustment dial allows tighter control of airflow and cylinder speed than other flow control valves. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

Elbow Air Flow Control Valves with Flow Indicator

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. Mount them 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.

Tamper-Resistant Air Flow Control Valves

Prevent accidental airflow changes with these valves, which require an adjustment tool to alter their flow rate. They control the speed of air-powered equipment by adjusting the volume of airflow.

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.

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-Operated Air Flow Control
Valves with Safety Shut-Off

Protect air-powered equipment in emergency shut-off situations—when system pressure drops, these valves automatically close to stop cylinder motion, even at mid-stroke. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

Corrosion-Resistant Single-Control
Two-Direction Air Flow Control Valves

Made of PBT, these plastic valves are more corrosion resistant than valves made of aluminum or nylon. A single dial adjusts airflow equally in both directions, controlling the extension and retraction speed of an air cylinder at the same time.

Precision Flow-Adjustment Valves

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.

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.

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.

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.

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.

Threaded Precision Flow-Adjustment Valves for Steam

Use these valves in applications with steam pressure up to 200 psi @ 450° F. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Flow-Adjustment Valves and Manifolds

Flow-Adjustment Valves

Manually adjust the flow of oil to a single lubrication point.

Electrically Operated Flow-Adjustment Valves

A solenoid automatically starts and stops flow to a single lubrication point to dispense lubricant while equipment is running.
