Company Profile

Relief valve is through the adjustment, the import pressure will be reduced to a need of the export pressure, and rely on the energy of the medium itself, so that the export pressure to maintain the stability of the valve automatically. From the point of view of fluid mechanics, the pressure reducing valve is a local resistance can change the throttling element, that is, through changing the throttling area, the velocity of the fluid and kinetic energy change, resulting in different pressure loss, so as to achieve the purpose of decompression. And then rely on the control and adjustment of the system, so that the pressure of the valve after the pressure fluctuations and the spring force balance, so that after the pressure of the valve in a certain range of error remain constant.
