1), 3), 5) Cooling water valve

The temperature of the secondary steam downstream the steam-conditioning stations is controlled by the cooling water control valves and is feeding the cooling water chamber or nozzle of the steam-conditioning control valve. (series: 8C, 6H, 190)

2) HP-LP Steam-Conditioning Station

The HP-LP station supplies the plant with low-pressure steam to meet the power plant’s own requirements when the turbine is not running or turbine tap pressure is insufficient.  ARCA steam-conditioning control valves, which minimize noise as far as possible for humans and the environment by using multi-stage perforated plug and cage combinations, provide ideal conditions for this. Steam pressure is reduced in the valve and cooled by injecting cooling water into the valve itself or at the valve outlet with respect to the operating data. (series: 510 to 580)

4) HP-MP Steam-Conditioning Control Valves

The HP-MP station supplies the plant with medium-pressure steam to meet the power plant’s own requirements when the turbine is not running or turbine tap pressure is insufficient.  Otherwise, same remarks apply here as with the previously described valve. (series: 510 to 580)

6) Bypass Station-Steam-Conditioning Control Valves

The bypass station takes up the excess live steam and typically leads it through a steam tube directly into the condenser, especially if the emergency tripping mechanism for the turbine is actuated. Thus, fast and precise actuation times are required, since this is a safety device to protect the plant and to avoid the blow-off of steam into the environment. (series: 560 to 580)
