This is a Self-Operated Water Pressure Reducing Valve, an automatic pressure-reducing valve designed specifically for water systems, operating without external power. It mainly consists of a diaphragm actuator (with adjusting spring) and a cast steel valve body:Driven by the water medium’s own pressure, it senses the outlet water pressure via the diaphragm actuator, and cooperates with the spring preload to automatically adjust the valve core opening, stably reducing high-pressure inlet water to the set low-pressure value. The external adjustment component allows on-site adjustment of pressure reduction parameters to adapt to different working conditions.
Made of cast steel, it is suitable for medium-low pressure working conditions in water systems. It is widely used in pipeline systems of urban water supply, HVAC, building water supply and drainage industries, avoiding high-pressure water impact on downstream equipment and ensuring stable water pressure.
