The push buttons that operate these valves are separate from the logic unit, allowing you to position them away from machinery. Since both hands are required to simultaneously press the buttons, they protect workers from accidental machinery start-up. 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 spring, so valves return to their starting position as soon as you release the actuator. In the off position, they exhaust air from the system, allowing equipment to reset so the action can be repeated.

Note: Valve is sold as a complete unit, consisting of one logic unit and two signal valves. Port size given is for the logic unit. Signal valve port size is 1/8 NPT female.

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

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 can be installed normally open to allow airflow until actuated, or installed to block airflow and until actuated. Return actuation is by spring, so valves return to their starting position as soon as you release the actuator. In the off position, they exhaust air pressure from the system to the atmosphere, allowing equipment to reset so the action can be repeated.

Often used to extend and then retract a cylinder at different speeds, these valves 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 5/2 valves.

Valves with spring return actuation return to their original position as soon as you release the actuator.

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. 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.
