Electric Actuated Valves

Electric Actuated Valves

African Valve is a premier Electric Actuated Valves Manufacturer in South Africa, delivering automation-ready valves for industries requiring remote control, precision flow regulation, and fast shut-off capabilities. Our electric actuated valves combine the reliability of industrial-grade valve designs with advanced electric actuators for seamless integration into automated process systems.

Function & Working

Electric actuated valves operate by converting electrical energy into mechanical torque to open, close, or modulate a valve. They enable automated control over fluid flow using signals from control systems, ensuring accuracy and responsiveness in pressure, temperature, or flow-sensitive processes.
