Declutchable override actuators are designed to provide manual override capabilities when air supply to the pneumatic actuator is interrupted. The "DG" series is a "sandwich" style declutchable worm gear designed to work in conjunction with pneumatic actuators.

These products have a locking engage/disengage lever mounted on a cam to provide positive engagement of the worm to segment in an emergency situation.

Declutchable manual override worm gears are available from stock with torque outputs ranging from 3000 in-lbs. to 26,000 in-lbs. These products are inventoried to provide a quick custom fit between actuators and valves.
