Electric Actuator

ALIS Valves offers Electric Actuators for industrial valve automation applications requiring reliable operation, precise positioning and convenient remote control. These actuators convert electrical energy into mechanical movement to operate compatible valves, including ball valves, butterfly valves and other quarter-turn or multi-turn valve designs, depending on the actuator type. Electric actuators can be configured for on-off operation or modulating control, allowing valves to open, close or adjust their position according to the control signal. Depending on the model, features may include an electric motor, reduction gearbox, position indicators, limit switches, torque protection and manual override for operation during power interruptions or maintenance. Suitable actuator configurations can also support integration with programmable logic controllers (PLCs), distributed control systems (DCS) and other industrial automation equipment.

Electric Actuators are used in water treatment plants, chemical processing facilities, oil and gas installations, power generation units, HVAC systems and industrial fluid-handling applications. They can be selected for compatible valve types and operating environments according to the required torque or thrust, operating time, duty cycle and control function. Important selection factors include valve size and design, operating torque, electrical supply voltage, frequency, control signal, required positioning accuracy, enclosure protection rating and ambient temperature. Buyers should also consider whether the application requires simple open-close operation or continuous modulating control, along with feedback signals, limit-switch arrangements and fail-safe requirements where applicable. The actuator must be correctly sized for the valve’s operating conditions and compatible with the mounting interface. Selecting the appropriate electric actuator helps support dependable valve automation, accurate positioning and efficient process control under the intended working conditions.
