Two-Action Air Directional Control Valves with Full Shut-Off
These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Also known as 4-way and 4/3 closed-center valves, they create two actions, such as extracting and then retracting a double-acting cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by hand, so valves stay actuated and return to their original position only when you move the actuator again.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Two-Action Air Directional Control Valves with Exhausting Shut-Off
In the off position, these valves exhaust all air pressure, allowing equipment to return to the neutral position. Also known as 4-way and 4/3 exhaust-center valves, they create two actions, such as extracting and then retracting a double-acting cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by hand, so valves stay actuated and return to their original position only when you move the actuator again.
