The actuators mainly include electric actuators, pneumatic actuators and hydraulic actuators:1. Electric Actuators: Electric actuators are mainly used in power plants or nuclear power plants because a smooth, stable and slow process is required in high pressure water systems. The main advantage of the electric actuator is the high stability and the...

Stainless steel electric ball valve is mainly used to cut off or connect the medium in the pipeline, can also be used for fluid regulation and control.It is mainly composed of ball valve and electric head.Main features of stainless steel electric ball valve:1. Thrust bearing reduces the friction torque of the stem, which can make the stem operate s...

Common causes of gate valve leakage gate valve leakage of the main reasons: one is the valve body, the valve body in the open surface, packing, bottom drain wire, flange sealing surface caused by leakage, two is the valve leakage. I. leakage caused by substandard valve quality Valve itself defect is mainly external defects, external defect...

The selection principle of valve electric actuator is as follows:1. There are two main machine structures for operating thrust valve electric device: one is not equipped with thrust disc and directly output torque;The other is provided with a thrust disc, the output torque is converted to output thrust by the stem nut of the thrust disc.2. Operatin...
