Our compact electric regulating valves feature a 30% weight reduction, 30% height reduction, and a 30% increase in flow rate from the original Cv3000 model. These are improved upon the Cv3000 base. The compact electric regulating valve boasts advantages such as a compact structure, lightweight, sensitive operation, large valve capacity, accurate flow characteristics, and easy assembly. Equipped with an electric actuator and feedforward function, it accepts unified 4-20mA or 1-5V·DC standard signals, converting current signals into corresponding linear displacements, automatically controlling the valve opening to continuously adjust process parameters such as pressure, flow rate, temperature, and liquid level within the pipeline. Widely used for accurate control of gases, liquids, steam, and other media, maintaining process parameters like pressure, flow rate, temperature, and liquid level at set values. Particularly suitable for applications with small allowable pressure differences and relatively small leakage volumes.
