 How to choose the rated pressure of pressure valve in hydraulic station?

   Hydraulic station Selection of rated pressure of pressure valve:

The rated pressure of the pressure valve in the hydraulic station is the basic performance parameter of the hydraulic valve, which indicates the pressure bearing capacity of the pressure valve, and refers to the nominal pressure of the pressure valve under the rated working state. The rated pressure of the pressure valve in the hydraulic station should be selected according to the designed working pressure of the hydraulic system. Generally speaking, the rated pressure value indicated on the pressure valve of the hydraulic station shall be appropriately greater than the working pressure of the system.

Selection of flow specification of pressure valve in hydraulic station:

The rated flow of pressure valve in hydraulic station refers to the nominal flow of hydraulic valve under rated condition.

The actual working flow of the pressure valve is related to the connection mode of the oil circuit in the system: the flow rate of the series circuit is equal to that of the parallel circuit, and the flow rate of the parallel circuit is equal to the sum of the flow rates of the oil paths. When selecting the flow specification of the pressure valve in hydraulic station, it is obviously the most economical to make the rated flow of the valve close to the working flow of the system. And the rated flow rate of the hydraulic valve may cause poor working quality. In addition, the flow rate of the valve can not be selected simply according to the rated output flow of the hydraulic pump, because for a hydraulic system, the flow through each circuit can not be the same. Therefore, the maximum flow rate of the circuit where the pressure valve is located should be considered when selecting.
