Low Force Rated Actuator for Steam Turbine Valve

Challenge

A customer needed a solution for a discontinued Tri-Sen actuator that controls a pilot valve for their steam turbine system. They tried a screw-type actuator for this system and ended up failing multiple times. They needed a simple solution that could handle the shock loads and controllability.

Kyntronics Solution

• Improved process control – using Position control
