  Precautions for outdoor installation

Please install a protective cover covering the entire machine to avoid direct sunlight and rain.


Please reserve the space required for incoming lines and manual operation.


Direct sunlight outdoors can cause high temperatures, leading to the aging and even failure of heating components. Rainwater will accelerate the aging of the rubber pad and instantly damage the product in case of improper waterproofing operation.


  Ambient temperature and fluid temperature conditions

The ambient temperature should be within the range of -20℃ to +60℃.


When used in environments with temperatures below zero or large temperature differences, models equipped with dehumidifying heaters to prevent condensation should be selected.


When the fluid temperature is relatively high, high-temperature type connection frames and joints should be used to install the drive device on the valve.


  Indoor installation precautions

This is a non-explosion-proof product. Do not install it in a room with explosive gases.


When in a place where water and raw materials may splash, please install a protective cover covering the entire machine to ensure safety.


Please reserve the space required for incoming lines and manual operation.


  Usage and Maintenance

Manual operation is prohibited when the power is on

This product has been comprehensively debugged and inspected by quality inspection personnel before leaving the factory. When installing and connecting the product with the valve, due to reasons such as the valve coupling, the valve may not be fully closed or fully opened and needs to be readjusting. The following steps should be followed during adjustment:

◆ Install and connect the actuator and the valve correctly;


◆ Manual trial run

Remove the electrical cover, take off the rubber plug of the handle shaft, insert the attached door corner handle into the hexagonal hole, and turn it clockwise. The valve opening degree should be reduced.

When the valve is in the fully closed position, observe whether the limit travel switch for the closing direction operates (a "click" sound will be heard when the switch operates), then turn the handle about half a turn to check if the mechanical stop block touches the adjusting screw.

Turn the handle counterclockwise to increase the valve opening. In the same way, check the limit travel switch and mechanical stop in the opening direction. After manual operation is completed, install the air cover and plug the rubber stopper.


◆ Electric trial operation

Remove the wiring cover and connect the wires correctly according to the circuit diagram on the cover.

Power on and conduct a trial run. Pay attention to observing whether the actuator and valves are working normally.


◆ Maintenance

In view of the compact structure of this product, molybdenum-based grease with long service life and good pressure resistance is specially used to achieve no need for oiling. When the electric valve does not operate for a long time or operates infrequently, please regularly check whether there are any abnormalities in the drive actuator.
