Electric Actuator

The Electrical Actuator is an electro mechanical device which is used to provide controlled movements which are operated manually, electrically and different fluids like air hydraulics and many more. It is mainly used for control as well as regulation gas fired appliances like burners, boilers, ovens and furnaces. Our Electrical Actuator are small, light weight, easy to install and maintain. According to different application, various models of Actuators available with adjustable high flow limit switch.
