AAK Cartridge Counterbalance Valve New Function Generated from SUN Model

Alek is from Poland and was annoyed when he first purchased hydraulic cartridge valves from Ningbo. In the second half of last year, they tested a hydraulic lift that used a hydraulic cartridge counterbalance valve purchased from a hydraulic cartridge valve manufacturer in Ningbo. When the load was lowered, the lift vibrated at low frequencies and the system was unstable. The customer was not satisfied with the prototype and requested that the hidden danger be resolved within 2 months, otherwise the order would only be cancelled. The original hydraulic cartridge counterbalance valve manufacturer reported that this function is a standard model benchmarking SUN Hydraulics and cannot be improved. Alek contacted other hydraulic cartridge valve manufacturers in Ningbo, but after a week, there was no result.

Alek contacted AAK through the introduction of peers. In my impression, AAK seems to have no Polish customer.
