Explosion Proof Exd CT4 Modulating Rotary Electric Actuator for Butterfly Valve

Brief introduction:

Offers a full line of electric actuators with torque ranges from 100 to 20,000 inch pounds in DC 12,24V,220V.AC24V,110V,220V,380V voltages. All electric actuators are available for modulating (4-20mA control) or on-off service. Fully adjustable limit switches allow for fine control of on-off positions. Options for NEMA 4, 4X and 7 enclosures provide flexibility for a variety of environments and applications. ISO mounting and a double star output shaft create direct mounting to a variety of quarter turn valves. We can provide a complete automated assembly with our Flowx ball valves and butterfly valves, or retrofit onto an existing valve with our customized mounting hardware.

 It has widespread use in many industries. Including: metallurgy, petroleum, chemical engineering, generating station, printing and dyeing, water treatment, shipbuilding, paper-making, food processing, pharmacy and building automation system etc. 

1, pneumatic butterfly valve and pneumatic ball valve;

Product Features:

1. Strong features: intelligent regulation type, proportion type, switch type various signal output type,  everything that you expect to find;

2. Small and light: it’s volume and weight are merely equal to about 35% of traditional products;

3. Elegant appearance: aluminum alloy cast shell refined and fluent reducing electromagnet tic interference;

4. Reliable performance: key components like shaft bearings and electrical elements are imported famous-brand produces;

5. High protection standard: IP 68 high standard protection level [detected by Shanghai instrumentation and autonomous system inspection and test institute);

6. Precise and wear resistant: The worm wheel output shaft adopts integrated forging from special copper base alloy, and has high strength and good wearability;

7. Extremely small return difference: its integrated structure avoids the gap of key-joints, and has high driving accuracy;

8. Safety guarantee: it has passed 1500 V voltage endurance detection, it has class F insulation electromotor, and it has CE accreditation, so it has higher safety guarantee;

9. Simple to mate: it adopts single phase power supply and simple connection loop, and we can also make it 380 V or DC

10. Convenient to use: no need to oil and no need to make spot-check, and it is waterproof and rust-proof, and can install at any angle;

11. Multi-speed: its whole range time is 9 Seconds, 13 Seconds, 15 Seconds, 30 Seconds, 50 Seconds, 100Seconds, and 150 Seconds (already set when leaving factory);

12. Intelligent digital control: the intelligent control module is integrated in the electric actuator, so it need not connect an external localizer; digital setting, digital calibration, high precision, self-diagnosis, and multiple - feature in one device. 

Installation environment requirement:

1. The product can be installed indoors or outdoors;

2. The product is not explosion protection product so please avoid flammable and explosive environment;

3. In an environment where there is rainwater, raw material splatter, and sunlight direct radiation on long term, you must install a protective hood to shield over the whole electric actuator.

4. Please reserve room for wiring, manual operation and installation and repair work;

5. Periphery environmental temperature should keep in 30 - 60℃range; Note: when using it in environment of big temperature difference or below zero point, you should use the model which has heater dehumidifier to prevent moisture condensation.
