| Message: | Nestor is from Greece. He has been purchasing hydraulic cartridge valves for 3 years smoothly. A hydraulic directional control cartridge valve bothered him recently. At the beginning of last year, the hydraulic directional control cartridge valve he purchased had leakage, which led to the loss of pressure in the oil circuit of the system. The root cause was the wear of the sealing ring. The original hydraulic directional control cartridge valve manufacturer said that the sealing is a standard O-ring and a single-side PTFE retaining ring, which is an industry standard. If there was a leak, it could only be replaced. It was not acceptable to replace it within 6 months. Nestor realized that this cartridge valve manufacturer was unreliable. |

Is this a real buying request?
