Message: | Muhammad is from a hydraulic equipment manufacturing company in Turkey. He has been purchasing smoothly for 3 years, but stumped by the valve spool of a hydraulic cartridge needle valve. At the beginning of last year, some of their customers complained that the positioning of the paper cutter was incorrect because of the leakage of the hydraulic cartridge needle valve. The original manufacturer said that the hydraulic cartridge needle valve spool was worn due to 24H operation of the equipment, which can only be replaced every 8 months, and can only guarantee the service life of 1 million times. The boss was not satisfied with the after-sales service of the original hydraulic cartridge needle valve manufacturer and asked Muhammad to find a manufacturer with a service life of no less than 2 million times. |
