A large-diameter electric flow regulating valve is an industrial equipment mainly composed of an electric (electronic) actuator and a large-diameter sleeve valve. It has the characteristics of compact structure, smooth flow channel, precise flow characteristics, wide adjustable range, and small valve seat leakage. Specially suitable for production process control systems for general fluid media and high flow process conditions in industrial sectors such as chemical, petroleum, metallurgy, and power plants.
When selecting a large caliber electric flow regulating valve, the following parameters need to be considered: flow, Pressure in front of the valve, differential pressure, Pressure and temperature behind the valve, etc. Selection and design need to be based on actual operating conditions and system requirements.
