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. Also known as pilot valves and 4-way valves, they use an air signal to actuate, so they're good for environments where electrical use may be dangerous. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion.

Valves without air-assisted spring return actuation go back to their starting position as soon as the air supply is removed.

Those with air-assisted spring return actuation require you to supply air to port P to go back to their starting position.

Valves with air pilot return actuation go back to their starting position when the air supply is moved from the first air pilot to the second air pilot.

NPTF (Dryseal) threads are compatible with NPT threads.

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

In the off position, these valves 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 actuate by air signal, so they're good for environments where electrical use may be dangerous. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by air, so they go back to their starting position when the air supply is moved from the first air pilot to the second air pilot. Also known as 4-way and 5/3 closed center valves.

These valves create one action, such as extending a cylinder. Also known as 3/2 or pilot valves, they use an air signal to actuate, so they're good for environments where electrical use may be dangerous. They direct airflow from an 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.

Normally closed valves normally block airflow, and remain closed until actuated. Valves that are both normally closed and normally open can be installed to normally block airflow, or to normally allow flow and remain open until actuated.

Valves with spring return actuation go back to their starting position as soon as the air supply is removed. Valves with air pilot return actuation go back to their starting position when the air supply is moved from the first air pilot to the second air pilot.
