common emergency stop valve.
• Hydraulically operated governing control and stop valves for reheat and LP admission steam
• Strainers for valves, steam traps and drain valves
• Exhaust casing relief diaphragm(s)
• Vacuum breaker
• Exhaust hood spray system
• Turning gear
• Noise enclosure
• Complete, fault-tolerant, electrohydraulic control (EHC) system with
o Vibration probes, axial position probes and monitoring system.
o Dual redundant differential expansion measurement
o Bentley Nevada TDXNET Module
• Lube oil conditioning system
• Static excitation system
