What is a regulated one in the power plant

1. Cooling water control valves (1, 3, 5)
The temperature control of the secondary steam downstream of the steam conversion stations is taken over by the cooling water control valves and fed to the cooling chamber of the steam conversion control valve. (Series: 8C, 6H, 180)

2. HP-LP steam conversion station (2)
The HP-LP station takes over the supply of the system with low-pressure steam for the power plant's own use when the turbine is at a standstill or when the turbine tapping pressure is insufficient. The ARCA steam conversion control valves, which keep the noise pollution for people and the environment as low as possible through multi-stage controlled perforated seat / perforated cone combinations, offer the ideal prerequisites for this. The steam pressure is reduced in the valve and, depending on the operating data, cooled by injecting the cooling water into the valve or into the valve's outlet pipe. (Series: 510 to 580)

3. HD-MD steam converting control valves (4)
The HP-MD station takes over the supply of the system with medium-pressure steam for the own use of the power plant when the turbine is at a standstill or when the tapping pressure of the turbine is insufficient. Otherwise, the same remarks apply here as for the valve described above. (Series: 510 to 580)

4.ULS Steam Conversion Control Valves (6)
The bypass station takes over the excess amount of live steam in the event of the turbine shutdown and usually drives it directly into the condenser via a steam outlet basket (steam tube). Otherwise, the same remarks apply here as for the valve described above. (Series: 560 to 580)
