NEUMAX QT SERIES QUARTER-TURN TRANSMISSION

NEUMAX QT SERIES QUARTER-TURN TRANSMISSION

Fig No.: QT Series

APPLICATIONS

NEUMAX “QT” series electric actuators are designed & engineered for robust, reliable and for high performance duty onto quarter turn valves.

The unique reliable motor module, adjustable cam plate limit switch, self locking mechanism, precision gearing system and ball bearings, the auto declutching mechanism, light force load on the handwheel, the adaptor drive bushing and bottom ISO 5211 mounting dimension, are added advantages against other make in the field of valve automation. CE approved.

It is suitable for used in heating, ventilation & air-conditioning, water treatment & water-works, power generation, petrochemical plants, oil storage facilities, chemical plants, effluent treatment works, pulp & paper mills, ship building industry, etc.

Features

MS QT Features Diagram

1. ENCLOSURE	Standard enclosure to water jet proof and water tight proof IP67, NEMA 4 & 6.
2. MOTOR	Squirrel cage motor is of encapsulated type, on high stall torque and low inherent force for seating and unseating of valves. All motors are integrated with build-in thermal protection.
3. TERMINAL CONNECTION & WIRING	Terminal connections are of “WAGO” push on type, making wiring connection very easy and without fuss. Electrical wiring circuit is standardized for single and three phare voltage. Addition termination is available on request.
4. INTERNAL COMPONENTS ARRANGMENT	Internal mechanical and electrical components are design in modular mounting arrangement, and can be easily remove for maintenance purposes. Additional optional accessories are also possible.
5. LIMIT SWITCHES	A pair limit switches are activated by means of simple, reliable and adjustable cam plates, mounted directly onto, and driven by center column. The unique cam plate design prevent over travel of limit switches.
6. TORQUE SWITCHES	Electric actuators of 100 N*m and above, are install with torque switches for over-load protection.
7. HEATER	For prevention of condensation due to weather and temperature changes, and also keeps internal components clean and dry, a 20 watt space heater is provided inside all the electric actuators.
8. SELF LOCKING MECHANISM	Self locking mechanism with improved worm gear design.
9. HANDWHEEL	Correct size of handwheel on the electric actuator ensure adequate strength for safe and efficient emergency operation.
10. MANUAL OVER-RIDE	Engage by pulling and piling the lever and turning the handwheel. Lever is auto declutch when power supply is switch on, and handwheel does not turn as extra safety feature.
11. VISUAL POSITION INDICATOR	The visual position indicator is directly mounted onto the center drive column to provide the visual position of the valve.
12. END STOPPERS	1 each for open and close position (adjustable), are for over travel protection.
13. MOUNTING & ADAPTATION	Bottom flange mounting dimension conform to ISO 5211. An adaptor drive bushing is provided for every electric actuator. It is removable and for machining to suite valve stem size.
