Fast-Switching Single-Action Electrically Operated Air Directional Control Valves
Run through equipment cycles up to 30% faster than with standard valves. They create one action, such as extending a 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 go back to their starting position as soon as voltage is removed. Also known as 3-way and 3/2 valves.
Normally open valves allow airflow until actuated. Normally closed valves block airflow until actuated.
Mufflers (sold separately) reduce exhaust noise.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Two-Speed Two-Action Electrically Operated Air Directional Control Valves
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 4-way and 5/2 valves, they actuate when voltage is applied to the electrical connection. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion.
Valves with spring return actuation go back to their original position when voltage is removed.
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.

Operated Air Directional Control Valves
Run through equipment cycles up to 30% faster than with standard valves. These valves shift between flow positions in 1.7 ms.

Also known as 4-way and 5/2 valves, they actuate when voltage is applied to the electrical connection.

Modular Air Directional Control Valves with Air Manifolds
Mount valves to a single-station base or to a manifold, which allows a single pressure source for multiple valves, then add or remove valves as your needs change. Valves with the same style can be used on the same manifold. For example, you can put a Style B, 2-position, spring-return valve and a Style B, 3-position, solenoid-return valve on the same manifold.
4-way valves create two actions, such as extending and retracting a double-acting cylinder.
5/3 (closed center) valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. 5/3 (exhaust center) valves exhaust all air pressure in the off position, allowing equipment to return to the neutral position. 5/3 (pressure center) valves create two actions at the same time, such as extending two single-acting cylinders at once.
Valves with spring return actuation go back to their original position when voltage is removed. Valves with electric (solenoid) return actuation go back to their original position when voltage moves from the first solenoid to the second solenoid.
