Summary:

    ZT electric actuator is used for control 0 °～270 °rotation of the valves and other similar products, such as butterfly valve, ball valve, damper, flapper valves, cock valves, etc. It’s widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, light industry and other industries. It drives by 380V/220V/110V AC power. Control signal is 4-20mA current signal or 0-10V DC voltage signal, enables move the valve to the desired location, achieving its automation, maximum output torque is up to 4000N·m.

Features:

1. Shell

  The shell is made of horniness auminium alloy, pass through anodic oxidation treatment and polyester powder coating, so it has strong corrosion resistance. Protection grade is IP67,NEMA4 AND 6, and optional IP68 type.

2. Electric Machinery

Fully enclosed Squirrel-cage electric Machinery, small volume, large torque, and small inertia force, F-class insulation rating, Inside hot protection switch, avoid damaging the electric machinery. 

3. Manual Structure

The design of handle ensure safe, reliable, labor-saving, small volume. When it don’t have electricity, it can be manually operated by handle. When you don't operate by manus, you can put the wrench in the wrench folder, then you can use it. 

4. Indicator

Indicator installes in the center axis, so it can observes the valve position. It adopts convex mirror design, no cumulate water, more convenient to observe. 

5. Desiccator

It is used for control temperature, avoiding internal moisture of electric actuator condensed because of the changing of temperature and weather,keep inner electric device dry.

6. Sealing 

Good sealing performance, and the protection class of standard product is IP67, and optional IP68 protection grade. 

7. Limit switch 

Mechanical, electronic double limit. Mechanical limit screw is adjustable, safe and reliable; electron limit switch is controlled by the cam mechanism, easy adjustment institutions can set the position accurately and conveniently, and it doesn’t affect overly by handwheel. 

8. Self-locking 

Exact worm and worm gear can efficiently transfer large torque, high efficiency, low noise (max. 50 dB), long life, and it has self-locking function to prevent the inversion, transmission part is stable and reliable, no need to add oil. 

9. Anti-off bolt 

When Removed the shell, the bolt would be attached to the shell and didn’t fall off.

10. Install 

The installation size of the bottom conforms to the international standard ISO5211 / DIN3337, The holes are double square so that it’s easy to fix the linear or 45°corner valves attached square bar, adaptable. It can be installed vertically, also can be installed level. 

11. Circuitry 

Control circuit conforms to the single-phase or three-phase power supply standard, reasonably compact line layout, wiring terminals can effectively satisfy a variety of additional functional requirements.
