Pressure relief valve working principle / relief valve working principle

The working principle of the ZJY46H combined pressure reducing valve is that the pressure of the regulating cavity is controlled by the control valve and the jet pump on the feedback system so that the pressure of the pressure regulating cavity is balanced with the main spring pressure.

Since the main spring pressure is not affected by the inlet pressure P1 , when the P1 inlet pressure and flow rate change, the balance between the main spring pressure and the pressure regulation chamber can always be quickly adjusted, so that the P2 outlet pressure and flow rate remain stable.

Because of the excellent combination ZJY46H valve works, so that large pressure reducing valve combined ZJY46H ratio can reach 12: 1
