The ZDHN electric double-seat control valve features a dual-guide structure, offering compact design, lightweight construction, responsive operation, high valve capacity, precise flow characteristics, and easy disassembly. This electric double-seat control valve incorporates our company's independently developed double-seat valve body and a linear-travel electric actuator. The electric actuator integrated into the valve incorporates a servo amplifier. It accepts standardized 4-20mA or 1-5V DC signals, converting electrical input into corresponding linear displacement to automatically regulate valve opening. This enables continuous adjustment of process parameters—including pressure, flow rate, temperature, and liquid level—within pipeline fluids. The electric double-seat control valve is widely used for precise control of gases, liquids, steam, and other media, particularly in applications with significant pressure differentials and where strict leakage control is not required for cle
