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.

Fast-Switching Two-Speed Two-Action Electrically
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. 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. 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. Return actuation is by spring, so they go back to their starting position as soon as voltage is removed.

Two-Speed Two-Action Electrically Operated Air
Directional Control Valves with Exhausting Shut-Off
In the off position, these valves exhaust all air pressure, allowing the equipment to return to the neutral position. 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. Also known as 5/3 exhaust-center 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. Return actuation is electric (solenoid), so they go back to their original position when voltage moves from the first solenoid to the second solenoid. Solenoid connectors are not included for NPT × NPT valves.

Single-Action Electrically Operated Air Directional Control Valves
These valves create one action, such as extending a cylinder. Apply voltage to the electrical connection to actuate. Also known as 3-way and 3/2 valves, they direct airflow from the inlet to your equipment and exhaust return airflow to create motion. In the off position, they exhaust air from the system, allowing equipment to reset so the action can be repeated.
Normally closed valves block airflow until actuated.
Valves with spring return actuation go back to their original position when voltage is removed.

Single-Action Electrically Operated Air Directional Control Valves with Full Shut-Off
Also known as 3-way and 3/3 valves, these valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. They create one action, such as extending a cylinder. Apply voltage to the electrical connection to actuate. 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 they go back to their starting position as soon as voltage is removed.

Electrically Operated Air Directional Control Valves with Flow Control
Create motion and control the speed of that motion with a single valve. Also known as 4-way valves, these valves create two actions, such as extending and retracting a double-acting cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion, and adjust the volume of air exiting an air cylinder (meter out) to control speed. Apply voltage to the electrical connection to actuate.
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 (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.

Wear-Resistant Electrically Operated Air Directional Control Valves
Ceramic plates form a longer-lasting seal against oil and dust than rubber seals that deteriorate over time. These valves withstand use in corrosive, dusty, and dirty environments such as foundries, paper mills, and steel plants. 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. Apply voltage to the electrical connection to actuate. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Also known as 4-way valves.
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.
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.
