Description
The El-O-Matic MO Series declutchable gear operators offer simple and reliable manual positioning
of valves, dampers and other quarter-turn devices when overriding, existing pneumatic or hydraulic
rotary actuators. All El-O-Matic MO-units are suitable for indoor and outdoor use and combine
rugged construction, light weight and modular design to provide the most efficient and cost effective
solution to a full range of manual override requirements.
The self-locking worm gear design means safe and easy operation, positive manual positioning and
extremely long life.
The El-O-Matic override can be adapted to any quarter-turn actuator and may even be installed in
the field on existing valves.
Operation
To engage manual operation, first pull out the spring loaded clutch lever, then rotate the clutch
lever clockwise until the clutch lever re-engages. Anticlockwise lever movement disengages manual
operation and returns the system to automatic operation.
Note: When under manual control, the valve remains locked in the last set position.
Stroke adjustment
The MO gearbox is equipped with two stroke adjustment bolts. These must be set for accurate
valve positioning and to avoid damage to the actuator or valve spindle during manual operation.
The limit stops on actuators are redundant in combination with MO-gearboxes. For stroke angle
less than 80° please consult our engineering department.
