| Message: | Yobachi, from Kenya, has not been working for a long time as a purchaser, and encountered difficulties in the hydraulic directional control cartridge valve. After 6 months of use, their hydraulic power unit has unstable operation. During after-sales checking, it was judged that that the main seal of the hydraulic directional control cartridge valve is worn, causing leakage and equipment failure. However, the hydraulic directional control cartridge valve manufacturer said that it had been nearly 1 year since the shipment, and he needed to purchase new ones again. Yobachi explained that taking the time on the delivery, transportation, assembly, equipment commissioning and inventory into account, the actual service life of this batch of hydraulic directional control cartridge valves was only 6 months. The boss was not satisfied that Yobachi had found an unreliable manufacturer. He had to re-purchase the hydraulic directional control cartridge valves with a service life of more than 1 year without leakage. Yobachi was under pressure. |
