Description of Characterisatics
1. Housing: Aluminum alloy Housing processed by hard anodizing and polyester powder finishing at a protection degree of IP67 (Namur&6) or IP68 has light weight, strong anticorrosive ability and applies to all kinds of harsh working conditions.
2. Motor: The specially designed squirrel-cage inductive motor has high startup torque and can reach top the maximum value soon after the start. It has overheat and overload protection unit set inside and boosts the high output efficiency, high accuracy and low noise.
3. PCU: High-performance integrated microprocessor saves complicated setting on site of installation. Its one-push automatic correction and self-debugging functions bring customers much convenience.
4. Sealing: Double O rings are used to realize two-way seal.
5. Manual Operation Mechanism: The manual operation is carried out by wrenching lever of clutch which will automatically restore to electrical control position upon power on. In addition, the handwheel is designed to drive the actuator easily, fast and conveniently, with its size determined according to the torque required to open the actuator.
6. Gear and Self-locking Device: The double-worm wheel and worm system and secondary reduction gearbox can avoid inaccurate valve position caused by instant counter rotation of actuator and guarantee correct and sound valve position when power off. In addition, the device features high output efficiency and low noise.
7. Limit Switch: The limit switch with high accuracy can be easily used to adjust the open and close limit of the valve. Overload protection is provided against overlarge torque of valve to protect both the valve and actuator.
8. Anti-condensation Heater: Switch on at the temperature of 20℃ ±3℃ to avoid internal water condensation and switch off at the temperature of 30℃ ±3℃ . The power is off automatically when the temperature is too high.
9. Limit Bolts: The limit bolts control the stroke of actuator through the open and close positions of the actuator to avoid the worm and
worm wheel off the way.
10. Indicator: The operator can watch the accurate open position of the valve in distance by the relatively big indicating window.11. Terminal Board: The plug and play terminal board can be installed easily and conveniently. Each terminal compressed by spring guarantees firm wiring and can be used in shaky environment.
12. Wiring: The internal wiring is simple and clear and is easy for connection.
13. Connecting Shaft Sleeve: The connecting shaft sleeve can be dismounted for individual processing based on reality. The mounting base meets ISO5211 Standard and can be connected with valve easily.
14. Lubrication: All gears and transmission shafts apply CIATM221 grease and are lubrication and maintenance free for 5 years.
15. Anti-interruption Magnetic Ring: Effectively prevent the circuit being interrupted by the external magnetic field to guarantee stable and reliable operation of the electrical actuator
