Installation and maintenence
High temperature solenoid valve features: high temperature resistance, using metal hard sealing and improving the use temperature. Wear-resistant: material selection is reasonable, stem and guided sleeve use fluid lubrication to reduce wear and tear dexterously. High temperature solenoid valve installation: 1、When installation, solenoid valve coil should be up and maintain the vertical position, solenoid valve arrows or marks should be in line with the pipe flow, and it shall not be installed in a splash of water or leakage place. 2、solenoid valve working medium should be cleaned with no particle impurities, dirt on the surface of the internal part and filter, requiring regular clean. 3、 when solenoid valve is failure, in order to isolating solenoid valves on time, and to ensure system normal operation, it is best to install bypass devices 4、In the pipeline system, solenoid valve diameter installed in the branch path should be less than the main path valve diameter. 5、before the installation of solenoid valves, pipes must be cleaned. Recommended installing filter before the valve, steam pipe should be installed with traps. 6、It can not install valve on a pipeline lower cavity, so as to avoid steam condensation water, impurities and other sediments in the valve and hindering movement. 7、can not be used in explosion hazard occasions. 8、in the pipeline insufficient rigidity, it is recommended to use scaffold to fix before valve, to avoid vibration caused by solenoid valve work. 9、Before installation, pay attention to see the product label, carefully read the instructions to determine whether the products meet the using conditions. 10、pressure gauge should be installed before and after solenoid valve, in order to observe the pipeline pressure.
The use and maintenance of high-temperature solenoid valve:
1、it is recommended to use specifically-assigned person to take charge of the operation and maintenance. 2、After installing solenoid valve, it is needed to pass into media experimental actions many times, to confirm it is normal and then put into official use. 3、We should regularly clean inside and outside valve and the title of Pick-up surface dirt, pay attention not to damage the sealing surface. 4、when solenoid valve is not used for a long time, should close the manual valve before the valve, re-opened, the steam solenoid valve should rule out condensate cleanly, and make trial moves several times, to be put into use before switching is normal. 5、when solenoid valve is removed from the pipe and not in use, should clean the internal and parts, and use compressed air to blow and store. 6、When using time is longer, such as poor sealing between the piston and the valve seat, piston sealing surface can be re-polished, and then grinding with valve seat. 7、when working, you should pay attention to pressure gauge before and after the valves, require working pressure shall not exceed the rated pressure, the working pressure differential must within rated pressure range. When the working pressure exceeds the rated pressure or working pressure diferential exceeds rated pressure differential, the solenoid valve should be stopped, close the front and rear manual valve, to avoid solenoid valve explosion and leakage
