Water flow control valves are suitable for clean water, hot and cold circulating water and industrial water media, widely used in water supply and drainage, HVAC and industrial piping systems. Suitable for normal to medium temperature conditions, the working temperature is generally 0 ℃ to 80 ℃. The main function is to accurately regulate and control the water flow to ensure stable system operation and energy saving. The valve body material usually adopts ductile cast iron, stainless steel or copper alloy, and the seals are made of wear-resistant rubber or polyurethane, which has good corrosion resistance and sealing performance, compact structure, easy maintenance, and adaptable to a variety of complex working conditions.
