Introduction of YGa43H / Y high-sensitivity large-flow steam pressure reducing valve


高灵敏度大流量蒸汽减压阀 属于先导活塞式减压阀。 This series of high-sensitivity, high-flow steam pressure reducing valves are pilot-piston pressure reducing valves. It consists of a main valve and a pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. This product has been greatly improved on the basis of ordinary pressure reducing valves, increasing the area of the piston and changing the throttle structure. Changed the sealing form, increased the over-current area, etc., thereby greatly improving performance in terms of improving sensitivity, flow rate, and life.
This product is mainly used in steam pipelines. It is suitable for steam pipelines with large flow rates and large changes in inlet pressure.
