Electrical Air Directional Control Valve

Manufacturer part: 6425K27

These valves close all ports in the off position to 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. 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 and 5/3 closed center valves.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 is moved from the first solenoid to the second solenoidNPTF (Dryseal) threads are compatible with NPT threads.Manifold-mount valves plug into a manifold (sold separately) to create multiple actions from a single pressure input. Manifolds with multiple exhaust ports have one set of inlet and exhaust ports on each side, so they can be strung together in a series. When using a single manifold, cover the ports on the side you are not using with plugs (sold separately).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.
