Our ZRHM electric sleeve regulating valve is a high-performance electric regulating valve suitable for fluids under various pressures and temperatures and applications with less stringent leakage requirements. The electric sleeve regulating valve is composed of the valve body, valve seat, sleeve, valve stem, guide sleeve, valve cover, sealing material, and electric actuator. It drives the valve to change the cross-sectional area between the valve stem and seat to control the flow rate, temperature, and pressure of the pipeline medium, thereby achieving automated regulating functions by receiving signals from industrial automation control systems (e.g., 4-20mA or 1-5V). The fluid channel of the electric sleeve regulating valve is S-shaped, featuring low pressure drop loss, high flow rate, high flow characteristic accuracy, and a wide adjustable range. It boasts features such as sensitive operation, simple wiring, high flow rate, compact size, and high regulating accuracy. The electric sleeve regulating valve, electric balanced cage regulating valve, and electric single-seat sleeve regulating valve are widely used in automatic control systems in industries such as power, metallurgy, petrochemicals, boilers, light industry, and more.
