Atatürk, Turkey

A generating capacity of 2,590 MW and contributes about 8 billion kWh to Turkey’s electrical energy requirements.

The scope of supply includes eight Francis turbines equipped with electronic speed governors and eight biplane butterfly shutoff valves with a nominal diameter of 5,700 mm.

Practical Applications
