Product description
Y43H-25 type pilot valve piston steam: the flange connection, the piston type structure form, the valve seat sealing surface material for Cr13 stainless steel, nominal pressure PN25, body materials for WCB steam pressure reducing valve.
Y43H-25 type pilot valve piston steam from the main valve and pilot valve composed of two parts. Main valve mainly comprises a valve seat, the main valve disc, piston, springs and other parts. Mainly by the pilot valve seat, valve, diaphragm, spring, adjusting springs and other parts. This product in the ordinary pressure-reducing valve based on the improved greatly, increase the piston area, changing the throttle structure and seal form, increase the flow area and so on, in order to improve the sensitivity, flow, and other aspects of life greatly improved performance. Mainly used for steam pipeline, applicable to the traffic flow changes, the variation of the inlet pressure in steam pipeline.
