Notices
1. Only qualified personnel can have the authorization to operate these equipment
2. While above mentioned personnel is using the equipment, the relevant instruction manual and/or other product files should be always prepared in a way to make the requirements of this manual be followed
3. Before the power is on, please double check the input voltage, frequency and connections are right. Any motor damage caused by wrong wire sequence or wrong voltage, the manufacturer will not be responsible for the maintenance and replacement.
4. The connection bolts for connecting valves should not be less than Class 8.8.
5. The Electric cabinet cap and motor etc. sealing area should not be opened during cloudy or rainy days
6. Special motor was used for the electric actuator, the lasting time is short. Continuous working time should not be over the limit specified on the nameplate.
7. While the equipment is not usually used, it should be checked, maintained and activated on a regular basis. The recommend frequency is 1 time/month, and the duration should be less than 10 mins.
8. Electric related caps should not be removed at explosive environment while there is still electricity. Whenever someone want to open the electric cabinet cap, the power should be cut off.
9. The electric actuator should be stored inside a room with clean and dry condition prior to installation. If installed outside the room, it should be kept at a certain height away from the ground, and anti-humidity, anti-rain procedures should be performed.
10. While initial electric operation after installation or re-installation is required, the valve should be in the middle position to check the open/close direction. Tests should be performed one by one according to the commissioning procedure and all parts should be checked at normal status prior to using.

Applications
Widely applied in various industries such as power station,petroleum,chemical industry,building,water treatment,urban construction,etc.
