According to the process conditions, select the appropriate structure and material.

The control valve is an actuator in the automatic control system, and its application quality directly reflects the regulation quality of the system.

There are various types of control valves, and their applicable occasions are different. Therefore, the type of control valve should be reasonably selected according to the require

It is advisable to choose a stop valve on the pipeline or device of high temperature and high pressure medium.

When installing the valve, pay attention to the flow direction of the medium, and install it strictly in the direction indicated by the valve flow direction arrow.

Open and close without friction. This function completely solves the problem of traditional valves affecting sealing due to mutual friction between sealing surfaces.

The working principle of the electric stop valve is to rotate the valve to open or block the valve.

The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

Globe valve, also known as stop valve, is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak.

The installation position, height, and entrance and exit directions must meet the design requirements, and the connections should be firm and tight.

Generally, gate valves have two sealing surfaces, and the processing and manufacturing are more complicated than globe valves.

The internal medium channel of the valve body is straight, the medium flows in a straight line, and the flow resistance is small.
