SD series quarter-turn electric actuator serves as a key terminal control component in industrial process measurement and control systems. It converts system control signals, including analog and discrete signals, into mechanical rotary displacement and output torque, so as to adjust the opening of valves or drive other regulating devices, ensuring the controlled medium operates under the conditions set by the control system.
As an important execution unit in industrial automation instruments, the intelligent electric actuator accepts control signals from regulators, PLC, DCS, and upper computers to fulfill automatic regulation tasks. It has become an essential part of modern automatic control systems.
It is widely applied in various industries such as power generation, metallurgy, petroleum, chemical engineering, mining, light industry, pharmacy, gas supply, building materials, transportation, urban subway, water supply, and sewage treatment.
