Standard Manual Override
If the isolation Safety Option is not required the standard manual override is available.
In auto mode, the actuator drives the valve using air entering through the Pressurized Air port and the Actuator/Solenoid port.
To switch to manual mode, the declutch bar is lifted and air is automatically released from the Actuator/Solenoid port and blocked from entering through the Pressurized Air Port. This simple and efficient release of air makes operation of the gear easier and safer.
