Adjustable pneumatic valve operation troubleshooting method < / div >

regulating pneumatic valve suddenly stopped in the operation process, the following several ways to help you right now, the other small make up warm reminder: adjust the pneumatic valve in use process, please don't big adjustment, because chances are you're adjusting the regulating pneumatic valve flow is not stable, in order to ensure that in use process can run normally, please use within the range of pneumatic valves under.

a, pneumatic valve body wall, about using in high pressure and corrosive medium regulation of pneumatic valve, pneumatic valve body wall were often medium impact and corrosion, it is necessary to focus on check pressure, corrosion condition.
2, pneumatic valve seat, regulating pneumatic valve in the assignments, for medium infiltration, fixed pneumatic seat within the thread with appearance is susceptible to corrosion and make the pneumatic valve seat is loose, should be pay attention to check. To work under high pressure difference of pneumatic valve, but should also view the pneumatic valve seat sealing surface is not bad.
3, pneumatic valve, pneumatic valve core is to adjust the moving parts of the pneumatic valve operations, the scour of the medium, the corrosion is most serious, carefully check the pneumatic valve core parts maintenance isn't corrode, wear and tear, especially under the condition of high pressure difference of pneumatic valve core wear more serious, ( Due to cavitation sight) Should be pay attention to. Pneumatic valve core damage should be replaced when serious. Also should pay attention to the scene of a pneumatic valve rod is similar or pneumatic valve core cohesion and loose, etc.
4, type o sealing ring and other gasket is ageing, crack damage.
5, should pay attention to ptfe packing, sealing grease is aging, mating surface is damaged, should be replaced when necessary.
