The main purpose
The desuperheating water regulating valve is used in large and medium-sized generating units to control the flow of desuperheating water required for the boiler main steam and reheat steam temperatures. It is one of the key regulating valves in power plants.
Features
• The valve body and valve cover are integrally forged, and other pressure-bearing parts are forged, with uniform structure and beautiful appearance;
• The internal parts adopt a press-fit porous superimposed pressure reduction structure, changing the traditional one-time pressure reduction into multiple pressure reductions. It has a compact structure, anti-cavitation, low noise, and easy installation and maintenance;
• The valve cover and internal parts adopt stepped limit seals, and the valve stem packing adopts a combination of V-shaped flexible graphite and reinforced molded graphite to improve sealing performance;
• The regulating valve can be equipped with our pneumatic actuator, or other brands of pneumatic, electric or hydraulic actuators according to customer requirements.
