The ZDHJP compact electric control valve features a 30% reduction in weight, 30% reduction in height, and 30% increase in flow capacity compared to the original Cv3000 model. It represents an enhanced version of the Cv3000. This compact electric control valve offers advantages including a compact structure, light weight, responsive operation, large valve capacity, accurate flow characteristics, and easy disassembly/assembly. Equipped with an electric actuator incorporating servo functionality, it accepts standard 4–20mA or 1–5V DC signals. It converts the electrical signal into corresponding linear displacement, automatically controlling the valve opening to achieve continuous regulation of process parameters such as pressure, flow rate, temperature, and liquid level within the pipeline.
