Electric Actuated Valve

Electric actuated valves combine an industrial valve with an electric actuator that converts electrical energy into mechanical movement to open, close or position the valve. Electric Actuated Valve Manufacturer in South Africa provide automated valve configurations for water treatment, mining, oil & gas, petrochemical, power generation, chemical processing and industrial applications.

How Electric Actuation Works

An electric actuator uses a motor and drive mechanism to generate the torque or thrust required to operate the valve. The actuator receives an electrical command and moves the valve to the required position. Quarter-turn actuators can operate ball, butterfly and plug valves, while multi-turn configurations can operate gate and globe valves.

Electric actuators are available for on-off operation and modulating control. Depending on the actuator, features can include limit switches, torque protection, position indication, position feedback and manual override. Modulating configurations may use 4-20 mA or other compatible control signals for valve positioning.

Testing & Standards

Testing may include pressure testing, seat leakage testing, dimensional inspection and actuator functional testing according to applicable valve and project requirements. ISO 5211 may apply to part-turn actuator attachment, while ISO 5210 covers multi-turn actuator attachments. IEC 60534 may apply where the electric actuated valve is specifically an industrial-process control valve.
