Made in China ZAYKA Electric Actuator

Product Description

  Summary

Our company electric actuator is used for controlling 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 position, achieving its automation, maximum output torque is up to
6000N·m..
2.Performance Features

2.1 Shell
The shell is made of horniness aluminium alloy, pass through anodic oxidation treatment and polyester powder coating, so it has strong corrosion resistance. Protection grade is IP65,NEMA 4 and 6, and optional IP68 type.

2.2 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.

2.3  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 spanner in the spanner folder, then you can easy to use it.

2.4Indicator

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

2.5Space heater

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

2.6  Sealing

Good sealing performance, and the protection class of standard product is IP65, and optional IP68 protection grade.

2.7 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.

2.8  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.

2.9 Anti-off bolt
When removed the shell, the bolt would be attached to the shell and didn’t fall off.

2.10Install

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, and also can be installed level.

2.11 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.
