Eaton Launches Precision Electric Valve Actuator for Industrial Use

In extreme environments where system failure is not an option, the precise control of critical valves can mean the difference between normal operation and catastrophic consequences. Eaton has addressed this challenge with a new electric valve actuator designed specifically for valves requiring 90-degree rotational movement, engineered to deliver exceptional performance and reliability.

The actuator utilizes advanced motor drive technology, available in either 28 VDC single-motor or dual-motor configurations. Multiple form factors accommodate diverse application requirements. The system employs worm gear and/or planetary gearbox mechanisms to achieve precise valve positioning. In the dual-motor design, Eaton incorporates a differential mechanism that allows continued operation even if one motor fails—a critical redundancy feature for mission-critical systems.

The actuator delivers:

• Rotation Range: 0-90 degrees with position indication
• Power Input: 28 VDC
• Actuation Time: 3-5 seconds

Position limits are managed through microswitches, Hall-effect sensors, or potentiometers, ensuring precise stopping accuracy. The system provides both visual and electrical position indicators for operational monitoring.

Designed for demanding sectors including aerospace, defense, and industrial automation, the actuator performs critical functions in aircraft fluid systems (fuel, hydraulics, air control) and industrial process applications where reliability directly impacts safety and productivity.

This development represents Eaton's ongoing investment in fluid control technology, focusing on enhanced reliability, safety, and operational efficiency. The company continues to explore advanced integration with emerging technologies including IoT connectivity and smart system architectures to meet evolving industry requirements.
