Electric pressure reducing valve is mainly composed of two bodies, two, a valve, valve cover and other parts group Granville, with two seats and a conical plunger structure. Increase the flow area and adjustable ratio. Are arranged in the valve throttle plate. Add feet pressure amplitude, while avoiding desuperheating water injected directly into the valve body, a valve body protection. Electric pressure reducing valve is mainly used for power matching in the third generation of desuperheating decompression device, adjustment of pressure and temperature using a temperature adjustment to and supporting the use of feed water regulating valve.
