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-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-Speed 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. 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 direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Also known as 4-way and 5/3 closed center valves.
Valves with spring return actuation go back to their original position as soon as you release the actuator.
Valves with hand return actuation stay actuated and go back to their original position only when you move the actuator again.

Multiple-Position Single-Action Air Directional Control Valves
Control six different outputs from a single source of airflow. These valves have one inlet port and six outlet ports. Push in and rotate the dial to move between outlet ports and send airflow to a different output. Also known as 3-way 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. Return actuation is by hand, so the chosen output remains actuated until you move the dial to another position. Air pressure exhausts to the atmosphere once a new position is selected.

Safety-Lockout Single-Action Air Directional Control Valves
To prevent accidental start-up, these valves can be locked in their off position with a padlock. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. They're normally closed to block airflow until actuated. Return actuation is by hand, so they stay actuated and return to their starting position only when you move the actuator again. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated. They help meet OSHA 29 CFR 1910.147 procedures for the control of energy sources that could injure workers.

Single-Action Air Directional Control Valves
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.
Normally closed valves block airflow until actuated. Valves that are both normally closed and normally open can be installed to block airflow, or allow air to flow until actuated.
Valves with hand return actuation stay actuated and go back to their starting position only when you move the actuator again.
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.

Simultaneous Two-Action Air Directional Control Valves

Safety-Lockout Air On/Off Valves
A padlock (not included) locks the handle of these valves in the shut-off position. When valves are closed, the exhaust port vents air pressure so you can disconnect air tools safely. They meet OSHA lockout requirements to maintain safety and control in a compressed air system.
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.

Quiet Safety-Lockout Air On/Off Valves
The muffler on these valves reduces exhaust noise. A padlock (not included) locks the handle in the shut-off position to disconnect air tools safely. They comply with OSHA 29 CFR 1910.147 to maintain safety and control in a compressed air system.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
