The Acutrol Declutchable Gear Override sandwich mounts between a pneumatic quarter-turn actuator and a ball, butterfly, plug or damper valve. This rugged device allows for manual operation during installation, system testing and in the event of a supply air failure.
The DGO Series mounts directly to many of the most popular rack and pinion style actuators on the market, and does not require a bracket between the pneumatic actuator and declutchable override. The units come complete with a three-stage coupler that connects to the pneumatic actuator through the gear override and to the valve (or coupler).
Output torques range from 3700 in. lbs. to 50,000 in. lbs. and cover a broad range of pneumatic actuator and quarter-turn valve sizes that require the convenience of a manual override.
There are two series available. The DGO Series matches the ISO 5211 bolt and drive dimensions which include a large number of pnematic actuator manufacturers. The KGO Series includes four sizes and is designed for the popular 3-1/4” and 5” butterfly valve/direct mount configurations.
The BBV - Block and Bleed Valve shuts off the supply air and vents the pneumatic actuator, allowing manual operation (please see IOM 4007 for detailed information).
