Cair - Three Phase Electrical Actuator - Rotary

Enclosure

• Standard enclosure to water jet proof will water tight proof IP 67.NEMA 4&6

Motor

• Squirrel cage motor is of encapsulated type, on high stall torque and low inherent force for seating & unseating of valves. All motors are integrated with build-in thermal protection.
• Terminal Connection & Wiring
• Terminal connections are of "WAGO" push on type, making wiring connection very easy & without fuss. Electrical wiring circuit is standardized for single & three phase voltage. Addition termination is available on request.
• Internal Components Arrangement
• 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.

Limit Switches

• A pair of limit switches are activated by means of simple, reliable & adjustable cam plates, mounted directly onto, and driven by center column. The unique cam plate design does not allow over travel of limit switches.

Torque Switches

• Electric actuators on 100 N • m and above, are install with torque switches for over-load protection.

Heater

• For prevention of condensation due to weather& temperature changes, an d also keeps internal components clean & dry, a 20 Walt space heater is provided inside all the electric actuators.

Self Locking Mechanism

• Because of the worm gear design system, all the electric actuators are self-locking.

Handwheel

• Correct size of handwheel on the electric actuator ensure adequate strength for safe and efficient emergency operation.

Manual Over-Ride

• Engage by pulling the lever & turning the handwheel. Lever is auto declutch when power supply is switch on, and hand wheel does not turn as extra safety feature.

Visual Position Indicator

• The visual position indicator is directly mounted onto the center drive column to provide the visual position of the valve.

End Stoppers

• 1 each for open & close position (adjustable), are for over travel protection.

Potentiometer-Otional

• Is available on request, is to provide & transmit remote indication of valve position.

Mounting & Adaptation

• Bottom flange mounting dimension conform to ISO 5211. Aadaptor drive bushing is provided for every electric actuator. Is removable and for machining to suite valve stem size.
