For the Hydraulic Cartridge Pressure Control Valve with a durability of 2 million times, Leander onl

At the beginning of last year, Leander contacted me under the introduction of one of our old customers in Greece. I learned that their company sold a batch of large excavators to South America. During operation, the pressure supply is often insufficient. They know that there is a problem with the hydraulic cartridge pressure control valves, especially the valve body is obviously worn. The original manufacturer of hydraulic cartridge pressure control valve was evasive and regarded that the wear was caused by high-frequency and high-pressure work of the excavator, because the valve body was made of 11L44 steel, which was the industry standard.

According to the drawings and working condition parameters of hydraulic cartridge pressure control valve provided by Leander, the material selection is the key if the service life of this hydraulic cartridge pressure control valve is more than 2 million times.
