Compressed Air Control Valves

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.

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.

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.

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.

Dual-Control Two-Direction Air Flow Control Valves

Independently control the speed of airflow in two directions. These valves regulate the speed of airflow as it enters or exits equipment, and are often used to control the extension and retraction speed of an air cylinder at the same time.

Slow-Start Air Flow Control Valves

Prevent damage to your equipment by limiting startup airflow and then gradually raising the airflow rate to operating levels.

Safety-Lockout Air On/Off Valves

A padlock locks the handle of these valves in the shut-off position so you can disconnect air tools safely.

Quiet Safety-Lockout Air On/Off Valves

These valves have a muffler to reduce exhaust noise. A padlock locks the handle in the shut-off position so you can disconnect air tools safely.

Sliding-Sleeve Air On/Off Valves

Slide the knurled sleeve in one direction to stop flow, and slide it back to start flow again.

Timer-Operated Air On/Off Valves

Install these valves on your air tank outlet—at the end of the day, they automatically close to save energy.

Robot-Arm-Mounted Electrically
Operated Air On/Off Valves

With two 2-way integrated solenoid valves, these electrically controlled valves direct airflow to venturi pumps, which generate the suction you need to run end-of-arm tools, such as vacuum cups.

Foot-Operated Air On/Off Valves

Turn airflow on and off with your foot to keep your hands free to perform other tasks.

High Airflow Shut-Off On/Off Valves

Also known as air fuses, these valves close automatically to turn airflow off when air volume exceeds the shut-off flow rate.

Air-Exhaust Control Valves

Quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. Also known as quick exhaust valves.

Quiet Air-Exhaust Control Valves

A muffler reduces exhaust noise. Valves allow airflow into your equipment and then quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. Also known as quick exhaust valves.

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.

Air Flow Check Valves

These valves open to allow flow in one direction and close when flow stops or reverses direction.

Pressure-Relieving Air
Compressor Air Flow Check Valves

Release pressure in the line between a compressor and an air storage tank, making start-up easier on the motor. These valves open to allow flow into the tank and close when flow stops or reverses direction, preventing air from escaping the tank when the air compressor is not running.

Air Compressor Air Flow Check Valves

Prevent air from escaping an air storage tank when the air compressor is not running. These valves open to allow flow into the tank and close when flow stops or reverses direction.
