| Message: | Evander is from a hydraulic equipment manufacturing company in Greece. He has been in purchasing for 3 years smoothly. Last March, they tested a hydraulic power unit. The hydraulic pressure control cartridge valve used was from a local manufacturer. During equipment commissioning, the operation was unstable. The sensitivity of the hydraulic pressure control cartridge valve port became dull under the influence of oil pressure in the oil circuit when it is open or closed. The original manufacturer had no solution. Evander contacted several other hydraulic cartridge valve manufacturers for inquiry, but no result. He was very worried. |

Is this a real buying request?
