1、 Before installing the high-temperature electromagnetic valve device, carefully check the product label parameters and practical working conditions to see if the electromagnetic valve of the device meets the application requirements. It is recommended that users assign dedicated personnel to be responsible for operation and protection maintenance.

2、 This step is very crucial and easy to overlook. Electromagnetic valves are precision components, and the pipelines and overcurrent equipment need to be thoroughly cleaned before installation to completely remove impurities such as metal welding slag, residual raw materials, rust and scale in the pipelines. For media that may have impurities, filters should be installed in front of the valve, with a minimum of 100 mesh.

3、 When installing, it is necessary to avoid the deposition of steam condensate and impurities in the high-temperature solenoid valve. Be careful not to install valves at the bottom of the pipeline to avoid affecting the operation.

4、 In order to ensure the normal operation of the solenoid valve, the device needs to undergo 5-10 trial runs with the medium before it can be officially put into use.

5、 When doing homework, pay attention to the working pressure before and after the valve. The working pressure should not exceed the nominal pressure. When a small working pressure difference is required, the pipeline working pressure difference needs to be greater than the small pressure difference to avoid the failure of the solenoid valve. When the working pressure exceeds the nominal pressure or the large working pressure, the system should stop using, reduce the working pressure, or replace the high-pressure solenoid valve.

6、 During regular protection and maintenance, the dust and dirt inside the valve should be cleaned regularly. For example, please be careful not to damage the sealing surface between the mating surface of the screw cap and valve plug, as well as the suction surface of the static iron core and the dynamic iron core.

7、 When the medium of the high-temperature solenoid valve is thermal oil, when removing it from the pipeline, clean the internal components of the valve with carbon tetrachloride (CCL4), and store them with compressed air. When disassembling and cleaning, each component should be placed in order and then restored to its original state.

8、 When the high-temperature steam solenoid valve operates each time, it should first remove the steam condensate and gas, and then try again 5-10 times. Only after the operation is normal can it be put into use. When the electromagnetic valve stops using the heat transfer oil for a long time, the front and rear manual valves should be closed.
