The core function of a check valve (also known as a one-way valve) is to prevent reverse flow of the medium and ensure one-way fluid flow. It is widely applicable in various working conditions and will be introduced from multiple dimensions as follows:

Improving the reliability of check valves in extreme environments such as high temperature, high pressure, strong corrosion, low temperature, and high particle media requires multidimensional optimization from materials, design, process, monitoring

The failure of the sealing performance of gate valves can cause medium leakage, affect system operation, and pose safety hazards.

The sealing performance failure of gate valves is mainly caused by the following reasons

​As the core equipment for controlling fluid flow in industrial pipeline systems, the installation and maintenance quality of gate valves is related to the stability and safety of system operation.

As a key equipment for fluid control, gate valves play an important role in multiple industries, and the differences in demand among different industries have led to different development trends of gate valves.
