 Product Features 


This type of electric actuator is designed for quarter turn applications,

1. Body: body material is hard aluminum alloy, with hard anodic oxdization and Polyester powder coating, so that it has great corrosion resistance and protection class is IP67.

2. Motor: fully enclosed cage type motor is small in size and inertia, large in torque. Insulation class is F grade which can prevent motor over-heating;

3. Manual Override: small handle is reliable, energy-saving. It can be used for manual operation when electricity is off; In automatic operation, it can be fixed inside the clip for easy operation;

4. Indicator: indicator is assembled on center axis, valve position can be observed; Outside mirror design facilitates position observation and prevents water drops accumulation;

5. Enclosure: high sealing performance, standard protection class is IP67;

6. Limit Switches: mechanical and electronic position limit switches.Mechanica stop Iscrew can be adjustable; Electronic limit switches can be controlled by cam.Position can be set easily and accurately by simply adjusting the cam without any influence by handle;

7. Self Lock: accurate turbo-worm structure can output large torque with high efficiency and little noise (Max. 50 decibel). Service life is quite long. Its self lock function can stop reverse rotation. Drive part is stable and reliable without additional lubrication;

8. Captive Bolt: bolts won't fall off when cover is disassembled;

9. Application: bottom connection complies with ISO5211/DIN3337 Standard. Star square hole is easy for square valve stem linear or 45° rotation application; Both vertical and horizontal assemble are available;

10. Diagram: control diagram complies with single phase or three phase wiring standard, reasonable wiring diagram and connection terminal can meet requirement of other optional functions
