Product Description
Y43H-25 pilot piston steam pressure reducing valve: flange connection type, piston structure type, the valve seat sealing surface material is Cr13 series stainless steel, the nominal pressure is PN25, and the valve body material is WCB steam pressure reducing valve.
Y43H-25 pilot piston steam pressure reducing valve consists of two parts: main valve and 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, valve clack, diaphragm, spring, adjusting spring and other parts. This product has made great improvements on the basis of ordinary pressure reducing valves, increasing the piston area, changing the throttling structure and sealing form, increasing the flow area, etc., thereby greatly improving the sensitivity, flow, life and other aspects. Improved performance. Mainly used in steam pipelines, suitable for steam pipelines with large flow rates and large changes in inlet pressure.
