1. the body wall
For use in high differential pressure and corrosive media occasions solenoid valve, body wall, diaphragm membrane and the impact of the media are often subject to corrosion, must focus on examination of pressure, corrosion of the situation.
2. valve seat
Solenoid valve work, because of the media into the fixed seat inner surface with a screw loose seat leaving susceptible to corrosion, inspection should be noted. Working under high pressure differential valve, check valve seat sealing surface is also washed out.
3. spool
Valve to regulate the work of moving parts, by the media, erosion, corrosion is most serious, carefully check valve when repair parts are corrosion, wear and tear, especially in the case of high-pressure differential is even more serious wear spool (due to cavitation phenomena) should be noted. Valve replacement should be carried out badly damaged, the stem should also pay attention to whether a similar phenomenon, or loose connections, etc. with the spool.
4. Patch "O" rings and other seals. Solenoid Valve shall be submitted in the diaphragm, "O"-shaped seal is aging, cracking damage.
5. sealing packing
It should be noted PTFE packing, sealing grease is aging, with the surface is damaged, should be replaced when Coach Bags necessary.
