| Message: | Rex is a hydraulic valve wholesaler in Turkey. At the beginning of last year, their customer complained that the hydraulic cartridge relief valve, which has been used for less than 6 months, was stuck or worn, resulting in equipment shutdown. The original hydraulic cartridge relief valve manufacturer advised that under the equipment working condition of 450 bar, the hydraulic cartridge relief valve is likely to be abnormal, and the service life can be only guaranteed for 6-8 months. Rex realized that the hydraulic cartridge relief valve produced by this manufacturer was not reliable under high pressure. After checking with other hydraulic cartridge valve manufacturers, none of them was able to guarantee a service life of more than 1 year under 450 bar pressure. Rex was worried. |
