Pneumatic forged steel regulating valve
Classification:
Case description
Application
Desorption water regulating valve is used for large and medium-sized generator sets to control the flow of desorption water required by the boiler main steam and reheat steam temperature. It is one of the key regulating valves in power plants.
Characteristic
• Body and valve cover are forged as a whole, and other pressure parts are forgings with uniform structure and beautiful appearance;
• The inner part adopts the pressing type porous superposition step-down structure, which changes the traditional step-down for this step-down, with compact structure, anti-cavitation, low noise, easy installation and maintenance;
• The valve cover and inner parts are sealed with step type limit, and the stem packing is sealed with V-shaped flexible graphite and strengthened forming graphite to improve the sealing performance;
• Regulating valve can be equipped with our pneumatic actuator, or according to customer requirements with other brands of pneumatic, electric or hydraulic actuator.
