Compressed Air Control Valves

Air Flow Control Valves

Air Flow Control Valves

Control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

Air Flow Control Valves
with Flow Indicator

Air Flow Control Valves with Flow Indicator

A numeric indicator on these valves provides a relative measure of airflow, similar to the volume dial on a speaker, making it easy to set the same flow rate with each use. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

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.

Tamper-Resistant Air
Flow Control Valves

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 entering or exiting.

Corrosion-Resistant Air
Flow Control Valves

Corrosion-Resistant Air Flow Control Valves

Made of plastic and stainless steel parts, these valves have excellent corrosion resistance. They control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting.

High-Pressure Air
Flow Control Valves

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.

Two-Direction Air Flow Control Valves

Two-Direction Air Flow Control Valves

Unlike other flow control valves that control flow in one direction, these valves regulate flow as it both enters and exits equipment. They're often used to control the extension and retraction speed of an air cylinder.

Air-Operated Air Flow Control
Valves with Safety Shut-Off

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.

Slow-Start Air Flow Control Valves

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.

Air On/Off Valves

Turn airflow on or off with these valves.

Air-Exhaust Control Valves

Vent exhaust air from your system to the atmosphere to relieve pressure.

Air Directional Control Valves

Create motion in air-powered equipment by supplying air pressure to the right place at the right time.

Air-Pulse Flow Control Valves

Air-Pulse Flow Control Valves

Used in air-blowing applications, such as dryers and dust-collection systems, these valves produce regular pulses of air that reduce overall air consumption.

Air Flow Check Valves

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