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.

Matching Flow Diagrams to Replace an Air Directional Control Valve

Choosing an Air Directional Control Valve

Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Also known as pilot valves and 4-way valves, they use an air signal to actuate, so they're good for environments where electrical use may be dangerous. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion.

Valves without air-assisted spring return actuation go back to their starting position as soon as the air supply is removed.

Those with air-assisted spring return actuation require you to supply air to port P to go back to their starting position.

Valves with air pilot return actuation go back to their starting position when the air supply is moved from the first air pilot to the second air pilot.

NPTF (Dryseal) threads are compatible with NPT threads.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Two-Speed Two-Action Air-Operated Air Directional Control Valves with Full Shut-Off

In the off position, these valves stop equipment in a locked position with air pressure holding it in place. Often used to extend and then retract a cylinder at different speeds, they create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. They actuate by air signal, so they're good for environments where electrical use may be dangerous. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by air, so they go back to their starting position when the air supply is moved from the first air pilot to the second air pilot. Also known as 4-way and 5/3 closed center valves.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Single-Action Air-Operated Air Directional Control Valves

These valves create one action, such as extending a cylinder. Also known as 3/2 or pilot valves, they use an air signal to actuate, so they're good for environments where electrical use may be dangerous. They direct airflow from an inlet to your equipment and exhaust return airflow to create motion. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.

Normally closed valves normally block airflow, and remain closed until actuated. Valves that are both normally closed and normally open can be installed to normally block airflow, or to normally allow flow and remain open until actuated.

Valves with spring return actuation go back to their starting position as soon as the air supply is removed. Valves with air pilot return actuation go back to their starting position when the air supply is moved from the first air pilot to the second air pilot.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Air-Pulse Flow Control Valves for Filter Cleaning

Designed for use in dust-collection systems, these normally closed diaphragm valves periodically burst air to knock debris from filters. Connect the valve’s inlet port to your air supply, and connect the outlet port to the blow tube in your system.

A solenoid is required to actuate the valve.

Flow coefficient (Cv) is a measurement that indicates how much airflow a control valve can provide to your cylinder.

Rapid Air-Pulse Flow Control Valves

These valves convert a continuous steam of air into a series of rapid pulses, reducing air consumption by up to 50% and improving performance in air blowing applications such as cleaning and drying.

Valves with air-pilot actuation activate when they receive an air signal.

Normally closed valves normally block flow, remaining closed until actuated.

Flow coefficient (Cv) is a measurement that indicates how much airflow a control valve can provide to your cylinder.
