MO-D series


The MO-D series are rugged, industrial grade manual overrides, manufactured with a cast iron housing. All models in this series feature high performance bearings and a polyurethane coated finish.


The PRO-GEAR MO-D series is designed to provide a manual operation of 90° for shut-off valves which are equiped with a pneumatic- or hydraulic actuator.

The MO-D series is providing a declutchable design for use in all industries where a reliable operation of both double acting and spring return pneumatic actuators, as well as hydraulic actuators is required.

All units which are to be mounted between the valve and actuator will be be supplied with a (interchangeable) actuator mounting flange for flexible usage. Furthermore, all units can be supplied with the ISO drive shaft which is connecting the actuator with the valve.

Optionally, a 3/2 relief valve can be fitted on the housing in order
to automaticly evacuate air pressure from the actuator while engaging the manual override.
