A New Electro-Mechanical Approach to Failsafe Actuators in Gas Turbines

Moog has been involved in providing motion control for the Power Generation Industry for over a decade and has been a trusted partner of the leading builders of gas and steam turbines. Over our history Moog has provided over 10,000 servovalves to over 1,000 plants worldwide. Today we design complete control assemblies and unique products in both hydraulic and electric technologies for a variety of turbine control applications. In addition to understanding the design needs of the turbine manufacturers for enhanced safety, up-time, and space saving, we also have vast experience in helping power plants run effectively by facilitating commissioning, operations, maintenance, and troubleshooting motion control systems.

Traditionally most of the process valves on a turbine are hydraulically operated. In this industry, performance measures are closely related to production availability including maintenance hours and startup time. The concept of using an Electro-Mechanically (EM) operated valve is very appealing to the industry for following reasons:
