Introduction of Y43H / Y Pilot Piston Steam Pressure Reducing Valve

Y43H/Y型先导活塞式蒸汽减压阀 属于先导活塞式减压阀。 This series Y43H / Y pilot-piston steam pressure reducing valve is a pilot-piston pressure reducing valve. It consists of a main valve and a pilot valve. The main valve is mainly composed of valve seat, valve disc, piston, cylinder liner, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. 通过调节调节弹簧压力设定出口压力,利用膜片传感出口压力变化,通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小,实现减压稳压功能。 The diaphragm pressure reducing valve sets the outlet pressure by adjusting the pressure of the adjusting spring, uses the diaphragm to sense the change in the outlet pressure, and adjusts the size of the over-flow area of the main valve throttling part through the pilot valve opening and closing to drive the piston to achieve the function of pressure reduction and pressure stabilization. This product is mainly used for steam pipelines, super-decompression and voltage stabilization.
