Elements that are prone to noise in hydraulic devices are generally considered to be the pump and valve, and the valve is mainly based on the overflow valve and electromagnetic commutation valve. There are many factors that produce noise. The noise of the relief valve has two types of flow rates and mechanical sounds. The noise caused by oil vibration, hole, and hydraulic shock in the flow rate. The noise produced by the impact and friction of the parts in the mechanical sound.
