Water solenoid valve use and maintenance:
1, it is recommended to use the unit to send the person responsible for maintenance.
2, the solenoid valve is installed into the media need to pass several experimental action shall be put into use after confirming normal.
3, large internal and external valve should be cleaned regularly and the title of the pull side of the dirt, careful not to damage the sealing surface.
4, when the solenoid valve is a long time to do, should be closed before the valve manual valve, when re-enabled, steam solenoid valve should condensate removal and clean, and make trial action several times, only to be put into use after the switch to normal.
5, when the solenoid valve from the pipeline do not remove, the internal parts should be scrubbed and blowing with compressed air storage.
6, when used for a long time, such as a seal between the piston and the valve seat is bad, the piston sealing surface re-polished, and now seat grinding.
7, in operation, should pay attention to before and after the valve pressure gauge required working pressure must not exceed the rated pressure, working pressure must be within the rated pressure range. When the operating pressure exceeds the rated pressure or working pressure exceeds the rated pressure, the solenoid valve to stop using closed before and after manual valves, solenoid valves to prevent explosions and leaks.
