AAK Hydraulic Check Valve 2 Tests for Pressure Holding Zero Leakage

Esperanza is from Spain and has over 1 year of procurement experience from hydraulic cartridge valve manufacturers in China, which has been relatively smooth. At the beginning of this year, Esperanza encountered difficulties in purchasing the CV08-20 hydraulic check valve. She purchased 120 pcs of CV08-20 hydraulic check valves from an old supplier. After 4 months, 4pcs of the hydraulic check valves were found to have leaks, a less than 2% of leakage. The manufacturer of CV08-20 hydraulic check valves advised that he cannot guarantee that each hydraulic check valve has no leakage, but is willing to offer 4 pcs for free replacement. Esperanza's biggest concern is that the quality of this manufacturer is unstable, and they have to find another hydraulic cartridge valve manufacturer in China.
