Product Details

　　ZDLM electric sleeve regulating valveIt is a high-performance electric regulating valve suitable for various fluids with different pressures and temperatures, and for situations where leakage requirements are not strict. The electric sleeve regulating valve is composed of a valve body, a valve seat, a sleeve, a valve core, a guide sleeve, a valve cover, a sealing packing, and an electric actuator that are matched together. The electric sleeve regulating valve drives the valve to change the cross-sectional area between the valve core and seat by receiving signals from the industrial automation control system (such as 4-20mA or 1-5V) to control the flow rate, temperature, pressure and other process parameters of the pipeline medium, achieving automatic regulation function. The fluid channel of the electric sleeve regulating valve is S-shaped, with low pressure drop loss, high flow rate, high accuracy of flow characteristics, and wide adjustable range. The electric sleeve regulating valve has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high adjustment accuracy. ZDLMElectric sleeve regulating valveElectric balance cage type regulating valves and electric single seat sleeve regulating valves are widely used in automatic control systems in industries such as power, metallurgy, petroleum, chemical, pharmaceutical, boiler, and light industry.
