Pressure reducing valve performance:
(1) Pressure regulation range: It refers to the adjustable range of the pressure reducing valve output pressure P2, within which the specified accuracy is required. The pressure regulation range is mainly related to the stiffness of the pressure regulating spring.
(2) Pressure characteristics: It refers to the characteristic that the output pressure fluctuates due to input pressure fluctuation when the flow rate g is constant. The smaller the output pressure fluctuation, the better the characteristics of the pressure reducing valve. The output pressure must be lower than the input pressure—the set value does not substantially change with the input pressure.
(3) Flow characteristics: It refers to the input pressure-timing, and the output pressure changes with the change of the output flow g. When the flow rate g changes, the smaller the change in the output pressure, the better. Generally, the lower the output pressure, the smaller it fluctuates with the change in output flow.
