Electric desuperheater control valve is a kind of anti-cavitation multi-stage pressure reduction valve. The trim of  Electric desuperheater control valve adopts the multi-stage pressure reduction structure. The fluids will consume large amounts of energy after passing the circuitous channel, so that fluid velocity is controlled and cavitation damage is avoided. Considering the existing desuperheater control valves in power plants are installed on a horizontal pipeline, the Electric desuperheater control valve has two kinds of bodies such as "same level body" and "different level body". The same level body indicates the inlet and outlet pipes are on the same horizontal line, and the different level body means the inlet and outlet pipes are not on the same horizontal line.
