Two-Action Air Directional Control Valves


Also known as 4-way and 4/2 valves, these valves create two actions, such as extending and then retracting a double-acting cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Valves without an exhaust connection exhaust air to the atmosphere.
Valves with hand return actuation 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-Hand Two-Action Air Directional Control Valves

Since both hands are required to simultaneously press the buttons, these valves protect workers from accidental machinery start-up. Also known as 4-way and 4/2 valves, they create two actions, such as extending 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 spring, so valves return to their original position as soon as you release the actuator.

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.

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.

Two-Action Electrically Operated Air Directional Control Valves

Also known as 4-way and 5/2 valves, these valves create two actions, such as extending and then retracting a double-acting cylinder. Apply voltage to the electrical connection to actuate. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so they return to their original position as soon as voltage is removed.

Two-Action Foot-Operated Air Directional Control Valves



Also known as 4-way and 4/2 valves, these valves create two actions, such as extending and then retracting a cylinder. Use your foot to operate them, leaving your hands free to perform other tasks. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Valves without an exhaust connection exhaust air to the atmosphere.
Valves with spring return actuation return to their original position as soon you release the actuator.
Valves with a foot return actuation stay actuated and return to their original position only when you step on them again.
Optional safety guards prevent accidental valve actuation.

Directional-Control Screw-In Hydraulic Valves
Control the direction of flow or stop flow altogether with an electronic signal. These valves are also known as cartridge valves, and they screw into your mounting block.
Place four-way valves between the pressure source and a double-acting cylinder.
