Açıklama

Quarter-turn electric actuators are an essential component of industrial automation systems. They are commonly used for opening and closing valves, controlling door systems, and enabling other mechanical movements. Thanks to their compact and lightweight design, they can be easily installed even in limited spaces. They stand out with their high performance and energy efficiency, helping to reduce operating costs.

These actuators respond to various application needs by offering different load and speed options. Their long service life minimizes maintenance requirements and increases overall system efficiency.

Quarter-turn electric actuators are designed for on/off or modulating control of butterfly, ball, and plug valves as well as dampers in industrial process control applications. Manufactured to high quality and specification standards in accordance with industrial requirements, these actuators are widely used in harsh process conditions such as iron and steel, chemical, marine, mining, paper, and cement industries. They are also commonly preferred in water treatment and HVAC systems.

Manufactured in compliance with the ISO5211 flange mounting standard, these actuators allow direct mounting on valves produced according to this standard. In addition to standard On/Off and modulating control applications in high-precision and frequent cycling process lines, they also provide advanced valve control via industrial communication protocols such as Modbus and Profibus.

Quarter-turn electric actuators provide reliable and efficient solutions across a wide range of applications, from industrial plants to commercial buildings. They help modernize automation systems and improve overall efficiency.
