Automatic hydraulic control valve inlet and outlet pressure recommendation and cavitation diagram

Attention! When the inlet and outlet pressure ratio is very large, the opening of the main valve is relatively small, and the flow rate through the seat will be very large, high speed water impact the seat and the body cavity, at this time will produce serious cavitation damage. At the same time, it produces shaking and noise. The green area below shows where the valve can work safely. Therefore, it is suggested that customers select the pressure range of import and export according to the following table.
