Valve

One morning in the first half of this year, shortly after arrived at the company, the owner asked him to come to his office. He realized whether there was a complaint about the hydraulic valve. He saw that the technical director was also in the owner's office. It turned out that the hydraulic check valve installed on the hydraulic pump had leakage in different proportions. These hydraulic pumps were due to ship in 20 days. The owner asked him to purchase the qualified hydraulic check valve in 40 days, because their customer only gave the company a 4-week extension. The technical director informed that according to the on-site detection, about 20% of the hydraulic check valves had leakage. After dissection, it was found that the gap between the valve body hole and the valve spool of these leaking hydraulic check valves was uneven, and some even exceeded 40m. The gap dimensions are quite different. Sam immediately contacted the original hydraulic valve manufacturer and asked him to replenish 30% to replace those unqualified hydraulic check valves, but he was rejected. Per the original hydraulic valve manufacturer, these hydraulic check valves passed the inspection before delivery and the leaked hydraulic check valves were caused by their improper installation. In the end, the manufacturer didn't even reply to his email. was angry and had to find a new supplier of hydraulic check valve. which made him see the dawn and feel that hydraulic valve is different. He emailed us inquiry about the hydraulic check valve and truthfully informed us of the problems he encountered with the Chinese hydraulic valve manufacturer. After several rounds of and operating conditions provided by , promised him to offer qualified hydraulic check valve samples within 14 days. If the samples are qualified, the 30% of quantity that he needs can be delivered in 4 weeks. After 14 days, received the hydraulic check valve samples. There was no leakage after installation and commissioning, and the gap between the valve body hole and the valve spool of each hydraulic check valve could be stable within a range and uniform in size. The technical department told him that the standard deviation (sigma) accuracy of the clearance dimension of hydraulic check valve was more than 3 times higher than that of the original supplier. was surprised how hydraulic valve was different The whole line of production equipment of hydraulic valve is a high precision machine tool and processing center
