These declutch gear boxes are designed to be a manual override between a pneumatic actuator and a valve (usually a ball or butterfly valve). It has an air lockout/exhaust which when engaged blocks off the supply air and exhausts any air from the actuator. This then allows the hand wheel on the gear box to operate the valve manually.
