Under normal circumstances, if it is not tightly closed, first confirm whether the valve is closed in place, if it has been closed in place, there is still a leak can not be sealed, then check the sealing surface. The sealing pair of some valves is removable, so take it out for grinding and testing

With the rapid development of China's industry, pneumatic valves in metallurgy, petrochemical and other fields are more and more widely used, its stability, reliability is also becoming more and more important, its working status will directly affect the automatic control process, Xiaobian will elab

Pneumatic valve actuator fault solution will choose the more suitable pneumatic actuator, cost-effective pneumatic actuator, then we must first understand the type of actuator, the actuator can be divided into pneumatic actuator and electric actuator, the more commonly used actuator is these two kin

Valve actuators are devices used to control the opening and closing of valves, usually including electric actuators, pneumatic actuators and hydraulic actuators. These actuators can be operated automatically or manually as needed and play an important role in a variety of industrial and commercial a
