The AMO declutchable Quarter-Turn Manual Override Worm Gearboxes provide a critical fail-safe for pneumatic(Rack and Pinion Actuator), hydraulic, and back-drivable electric actuators.
These "sandwich-mounted" units ensure uninterrupted manual control in the event of a loss in plant air supply, power gas, or electricity. Engineered for peak performance, the gearboxes feature high-efficiency internals that significantly reduce the handwheel effort required for operation.
