FAILSAFE ELECTRO- High performance electric technology for failsafe operation Hydraulic systems dominate various control applications in the power generation industry due to their capability to reliably shut down in failure situations. When a shutdown is required, hydraulic systems provide the ability to close valves against gas pressure. However, these same hydraulic systems pose cost, complexity and physical space challenges due to the implied need for hydraulic infrastructure. Moog has introduced an electric solution that eliminates the hydraulic infrastructure and provides safer, more compact and more cost-effective performance—plus the necessary failsafe protection in the event of an emergency shut-down. Moog's integrated solution includes an failsafe electro- mechanical actuator, Moog Motion Controller and Servo Drive as well as application software. Working in close collaboration with our customers, Moog engineers developed a patented, state-of-the-art solution: the first electro-mechanical failsafe mechanism to meet performance and safety requirements. In fact, Moog's electric solutions are approved to FM, CSA, and ATEX standards for use in hazardous areas. The solution reduces installation and maintenance effort bringing the advantages of electric control to the power generation market. • Ensures highest safety level via decoupled control and fast closing spring mechanism. • Eliminates potential fire hazards from high-pressure oil leaks. • Moog Servo Controller frees the processing power for other functions • Delivers clean energy and low maintenance costs of electric pneumatic auxiliary systems. • Helps to reduce the life cycle costs of the equipment: lower cost of • Enables preventative maintenance operational costs. • Steam turbine applications • Installation in harsh environments hydraulic actuators WHAT MOVES YOUR WORLD
