Small Size Key Box with 2PCS Manual Override Keys

Small Size Key Box with 2PCS Manual Override Keys

Autorun Manual Override devices are primarily intended as a safety back-up device, allowing for valve, damper or other quarter turn device operation in the event of a loss of air or power in a given plant, allowing operation of such items even when the driver, i.e. an actuator, is not responding. This also lends itself well to being used in the event of actuators being serviced.
