Structural characteristics of 
 This series of pressure reducing valves are pilot piston valve. Consists of two parts of the main valve and pilot valve. The main valve seat, the main valve plate, piston, springs and other parts. Pilot valve is mainly composed of the parts of the valve seats, valve, diaphragm, spring, adjusting spring. This product is made in the ordinary pressure reducing valve on the basis of greatly improved, to increase the piston area, change the structure of the throttle. Change the seal in the form, increase the flow area, thereby improving the sensitivity, flow, and other aspects of life has greatly improved the performance. 
 This product is mainly used for steam piping, apply to the traffic flow changes, changes in inlet pressure steam piping.
