Mix and match valve styles on one manifold to meet your control needs. Mount multiple valves to a manifold to reduce piping requirements and create multiple actions from a single pressure input. Add or remove valves as your needs change.
3-way valves create one action, such as extending a cylinder. They have four flow positions, which allows the valve to operate as two independent valves from a single station on the 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.
Normally closed valves block airflow until actuated.
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.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
