AAK solved the squeal of the hydraulic cartridge relief valve with a small trick, and Chapman abando

Chapman comes from a hydraulic equipment manufacturing company in Italy. However, the hydraulic pilot relief valves purchased at the beginning of the year has been in a big trouble, which makes his boss more and more disappointed with him. They sold a batch of hydraulic power units, and there was squeal or vibration. They judged that it was caused by the abnormality of the hydraulic pilot relief valve. However, when they tested the hydraulic pilot relief valve separately, the parameters met the standard, and no abnormality was found.

Chapman tried to source Chinese hydraulic valve manufacturers on Google. He was surprised that AAK's natural ranking in Google actually ranked on the home page. He left a message to ask if AAK could solve the squeal of the hydraulic pilot operated relief valve. I didn't answer yes or no, but only sent him two links about the squeal solution of the hydraulic valves.
