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.

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.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Because they require a key to operate, you can limit who is able to adjust these valves. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder.

Return actuation is by hand, so they stay actuated and return to their starting position only when you move the actuator again.

Air Directional Control Valves
Because they require a key to operate, you can limit who is able to adjust these valves. 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. Return actuation is by hand, so they stay actuated and return to their original position only when you move the actuator again. Also known as 4-way and 5/2 valves.
