Principle and definition of pressure reducing valve
2014-08-13 Number of attention:
According to the principle of action, the pressure reducing valve can be divided into automatic or movable type. The automatic pressure reducing valve is a valve which reduces the pressure at the inlet end of the valve to a required outlet pressure through the throttling action of the opening and closing parts (discs). When the pressure and flow at the inlet end of the valve change, the valve can use the energy of its own medium to automatically adjust the flow rate to keep the pressure at the outlet basically stable. He-movable pressure relief valve is a valve which converts the pressure change into electric signal, and controls the actuator to make the valve move by electric signal, and keeps the outlet pressure basically stable at the regulated value.
