:Q-Turn De-clutchable (MOR) Gear Operators:

The TRANSPOWER make gear units are Q-Turn De-clutchable (MOR) Gear Operators, specially developed to operate 90° movement valves along with pneumatic actuators. Precisely machined from the tested, quality raw materials, the operators are weatherproof. The alloy steel worm engages /disengages with the worm wheel depending upon the selector level position. Whenever there is service line (Electric or pneumatic) failure, the operator is put on the "Engaged" (or "ON") mode and the valve is operated via gear operator. Generally the gear operator is put on "OFF"mode.

INSTRUCTIONS FOR INSTALLATION "TRANSPOWER" Q-TURN De-CLUTCHABLE (MOR) GEAR OPERATORS

(a) Check the coupling pin dimensions and ensure they match with the gear unit being installed in the system.

(b) Bring the valve & the pneumatic actuator to the intermediate-position.

(c) Position the Gear Unit to `OFF' (i.e. `Pneumatic' Mode, where the gear unit is disengaged) by pulling-out the Locking-assembly pin & bringing the unit to `OFF' position by rotating the selector-lever.

(d) Assemble the valve, gear unit and pneumatic actuator firmly in position.

(e) Bring the gear unit to `ON' position (i.e. `Manual' mode, where the gear unit is engaged) by reversing the sequence explained in point (c) above.

(f) Check the operation of the valve by operating it thru gear unit and then set the mechanical-stoppers on the gear unit in proper position.

(g) Connect electric & pneumatic supply lines to the pneumatic actuator/ Solenoid valves.

(h) Bring the Gear-Unit to 'OFF' position as explained in point 'c' above and check the pneumatic-actuator/ Solenoid operation.

(i) Now the unit is fully assembled and ready to get into system.

• In 'OFF' mode, the system is operated by Pneumatic Actuator.

• In 'ON' mode, the system is operated by Gear-Unit.

• The Gear unit is filled with Multipurpose – S Grease prior to dispatch form the factory. It may need refilling after about two years for normal operation.
