About Directional Control Valves

Choose the right valve for your application by matching the actions you'll power to our flow diagrams.

Two-Speed Two-Action Air Directional Control Valves


Style C	Style D	Style E	Style G	Style K

Style L	Style M	Style Q	Style T

Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Also known as 4-way and 5/2 valves.

Spring Return—Valves with spring return actuation return to their original position as soon as you release the actuator.

Hand Return—Valves with hand return actuation stay actuated and return to their original position only when you move the actuator again.

Exhaust Connection—Valves with threaded exhaust connection type allow you to control the speed of each action by attaching a flow control valve to each exhaust port. Valves with no exhaust connection type exhaust air to the atmosphere.

Flow Coefficient (Cv)—Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

Manually control these valves by pushing or turning the actuator. Also known as 3-way or 3/2 valves, they create one action, such as extending a cylinder. They direct airflow from the 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. Valves without an exhaust connection exhaust air to the atmosphere.

Spring Return—Valves with spring return actuation return to their original position as soon as you release the actuator.

Hand Return—Valves with hand return actuation stay actuated and return to their original position only when you move the actuator again.

Valve Position—Fail-closed valves block airflow until actuated. Valves that are both fail closed and fail open can be installed to block airflow, or allow air to flow until actuated.

A simple automation solution that requires no programming, these valves are activated when an object, such as a box rolling on a conveyor, pushes the actuator.
