3-Way Normally Closed Control Valves
3-way normally closed control valves feature three ports within the valve body, which are used for pressure, output flow and exhaust. These valves are primarily used to operate single-acting actuators such as spring-return cylinders. We manufacture a wide variety of 3-way pneumatic valves, with options available to accommodate your application requirements.
