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.

Plastic On/Off Valves with Push-to-Connect
Fittings for Drinking Water

For a lightweight and economical alternative to metal, these valves are made of plastic. Insert tubing into the fittings—no heat, solder, or flux required. All meet NSF/ANSI 61 for use in drinking water systems.

On/Off Valves with Push-to-Connect Fittings

Insert tubing into the fittings on these valves—no heat, solder, or flux required. They’re for use with water, oil, air, and inert gas.

Plastic 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.

Easy-Set Threaded Plastic Precision
Threaded Flow-Adjustment Valves

To ensure consistent and repeatable settings, these valves have color-coded handle threads and numerical markings. One full revolution of the handle reveals a new color to indicate the set point. 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 Barbed Fittings

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 Push-to-Connect Fittings

Insert tubing into the fittings on these valves—no heat, solder, or flux required. They’re for use with water, 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 Chemicals

Use these valves with NPT threaded pipe. They have a fluoroelastomer seal and a plastic body to 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
Push-to-Connect Fittings for Chemicals

Insert tubing into the fittings on these valves—no heat, solder, or flux required. With a fluoroelastomer seal and a PVDF body, they 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 Barbed Fittings for Chemicals

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a PTFE seal and a PVDF body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves with
Barbed Fittings for Food and Beverage

These valves have barbed fittings that grip onto tubing, providing a secure hold. They’re often used in food and beverage tubing lines to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Precision Flow-Adjustment Valves with
Push-to-Connect Fittings for Food and Beverage

Insert tubing into the fittings on these valves—no heat, solder, or flux required. Designed for use in food and beverage tubing lines, they adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Diverting Valves with Barbed Fittings for Chemicals

Barbed fittings on these valves grip onto tubing, providing a secure hold. To divert flow between ports in chemical-processing applications, they have a chemical-resistant seal and a PVDF body to withstand aggressive and corrosive solutions.

Air Flow Control Valves

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 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.

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.

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.

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.

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.

Inline Corrosion-Resistant Air Flow Control Valves

Designed to be mounted inline, these valves can be placed in easy-to-reach locations. 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.

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.

Single-Control Two-Direction Air Flow Control Valves

Adjust airflow equally in both directions. These valves regulate the speed of airflow as it enters and exits equipment. They're often used to control the extension and retraction speed of an air cylinder at the same time.

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.

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.

Elbow Air-Exhaust Control Valves with Flow Control

Control the flow of exhaust air while also regulating the exhaust air speed. These valves dump exhaust air to the atmosphere without routing it back through a directional control valve. The 90° elbow shape allows you to install them in tight spaces. Also known as quick exhaust valves.
