Back from the three-day holiday, the director of the machine tool workshop sent a production report of TRV-08 hydraulic direct acting relief valve for an Indian customer early in the morning. The first paragraph is like this: "the programmers in our workshop made a low-level mistake and compiled the leakage of 2 drop / min in the hydraulic direct acting relief valve into a production process of 5 drop / min. I didn't check it out because I was anxious to go back to my hometown for the holiday". Seeing this production report of TRV-08 hydraulic direct acting relief valve, I was angry, not because the hydraulic relief valves produced has to be wasted, but because the workshop director indicated it as a low-level mistake in order to whitewash it. In every production link of hydraulic valves, error is error. There has never been any low-level error or high-level error. As long as you make a mistake, it's either bleeding or dying. I replied to him: 1. Re-produce TRV-08 hydraulic direct acting relief valve and work overtime continuously to make up for the the production progress delayed for 3 days. The produced parts of hydraulic relief valves shall be put into the waste warehouse and registered. 2. In the production of hydraulic valves, if you will make a mistake that no one has ever made, you can be promoted from workshop director to production director. The thought of predecessors is the ladder of future generations. To experience the pain of bleeding from mistakes, you can grow. No matter the production programming of hydraulic direct acting relief valves or other production links of hydraulic direct acting relief valves, we should not be careless. AAK hydraulic relief valves, it doesn't matter if there is a mistake. First recognize the mistake, then correct yourself, and then protect customers. You are welcome to try an order with AAK.
