Regulating valve series

The automatic control valve is a critical device in industrial automation for precisely regulating parameters such as medium flow rate, pressure, and temperature. Its core components include an actuator (pneumatic, electric, or hydraulic) and a valve body (e.g., single-seat, double-seat, or butterfly valves), which achieve precise adjustment by receiving control signals to modify the opening degree. Typical applications span chemical plants, power generation, and water treatment systems, suitable for air, water, steam, and corrosive media. Selection requires comprehensive consideration of functional requirements (e.g., shut-off or regulating type), drive method, medium properties (temperature, pressure), and flow characteristics (linear, equal percentage). Modern designs emphasize lightweight construction and high reliability, exemplified by fully functional ultra-light valves that simplify selection and enhance operational efficiency.
