Desuperheating water regulating valve, an anti-cavitation multistage throttle valve, also called high differential pressure regulating valve, is an automatic regulation device to reduce temperature of high pressure and ultra-high pressure generator set boiler. It controls the valve opening by vapor temperature, pressure and other parameter signals of the primary and secondary desuperheater for superheated steam in a boiler, and regulates feed water flow in the desuperheater of the boiler.

Features:

1. The valve adopts the form of multistage throttle with good regulation performance and good sealing.

 2. Throttling surface and sealing surface are separated; valve core and valve core set have been processed for hardening treatment of nitriding stone on the surface, and the hardness has reached around HRC70 with closing tight ness and long service life.
