Long-term use leads to wear:
During the use of the pressure limiting valve, due to the long-term influence of high temperature, high pressure, corrosion and other factors, its valve core, valve seat and other key parts are prone to wear, resulting in reduced sealing performance, thus causing leakage problems.
Material problems or manufacturing defects:
The materials of some pressure limiting valves may have certain defects or the manufacturing process is not sophisticated, resulting in cracks, pores, etc. during use, causing leakage.
Improper installation or maintenance errors:
During the installation or maintenance process, if the pressure limiting valve is not installed correctly or is damaged by external forces, it may cause its sealing performance to decline, causing leakage problems.
Influence of external environmental factors:
For example, the poor quality of the engine oil used for a long time may cause corrosion inside the pressure limiting valve; or environmental factors such as engine overheating and poor cooling system operation may also have an adverse effect on the operation of the pressure limiting valve.
