Block and Vent Valve

• Where the pneumatic actuator needs to be lated from the air control system of the plant, typically in the application of the valve + declutch manual override + actuator, Allied "Block and Vent" will help more in operation. This device provides a local means of blocking and venting the supply air from both solenoid valve and actuator, and at the same time venting all compressed air from both chambers of the actuator. This device is available both for double acting and spring return actuator.
