 What is a pressure reducing valve? What are the performance of a pressure reducing valve? Do you know? Today, let's get to know it together!

The pressure reducing valve is a valve that automatically maintains the outlet pressure by adjusting the internal pressure to the required outlet pressure and relying on the energy of the medium itself. From the perspective of fluid mechanics, the pressure reducing valve is a throttle element that can change the local resistance, that is, by changing the oil flow area, the flow rate and the dynamic energy change of the fluid, different pressure losses are generated to achieve the purpose of pressure reduction. Then rely on the control and adjustment system to adjust to balance the pressure fluctuation behind the valve and the spring force, so that the pressure behind the valve remains constant within a certain error range.

Performance of pressure reducing valve:

  1. Pressure regulation range: It refers to the adjustable range of the output working pressure P2 of the pressure reducing valve. The development within this research scope requires students to achieve the accuracy prescribed by the state. The pressure regulating range is mainly related to the stiffness of the pressure regulating spring.

  2. Pressure characteristics: Refers to the characteristics of output pressure fluctuations caused by input pressure fluctuations under the condition of constant flow g. The smaller the output pressure fluctuation, the better the performance of the pressure reducing valve. The output pressure must be lower than the input pressure, so that it does not change with changes in the input pressure.

  3. Flow characteristics: refers to the continuity of the input pressure and the output pressure changing with the output flow g when the input pressure is constant. When the flow g changes, the smaller the output pressure change is, the better. Generally, the lower the output pressure, the smaller the fluctuation as the output flow changes.

   The above is to introduce you to the pressure reducing valve and the performance of the pressure reducing valve, I hope it will help you!
