    About Directional Control Valves

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

    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.
    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.
    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.
