产品描述 Product Description
组合式高压差减压阀需要降低到一定范围的设备和管路系统上，通过调节将近口压力降低至某一需要的出口压力值。当进口压力或流量发生变化时靠介质本身的能量可自动保持出口压力在一定的范围内。
The combined high-pressure differential pressure reducing valve needs to be lowered to a certain range of equipment and pipeline systems, and the outlet pressure can be reduced to a desired value by adjusting the inlet pressure. When the inlet pressure or flow rate changes, the energy of the medium itself can automatically maintain the outlet pressure within a certain range.
