Turbine Bypass

1. Cooling Water Control Valves (I, III, V)
Temperature control of secondary steam behind the steam-conditioning stations is assumed by cooling water control valves. The steam is then fed to the cooling chamber of the steam-conditioning control valve (series 8C, 6H, 180).

2. HP-LP Steam-Conditioning Station (II)
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 perforated plugs and seat rings with graduated control, provide ideal conditions for this. Steam pressure is reduced in the valve and cooled by injecting cooling water into the valve itself or its exit line with respect to the operating data (series 510 to 580).

3. HP-MP Steam-Conditioning Control Valves (IV)
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, the conditions that exist for the aforementioned valve apply here as well (series 510 to 580).

4. Bypass Station, Steam-Conditioning Control Valves (VI)
The bypass station takes up the excess live steam and typically channels it through a steam tube directly into the condenser if the emergency tripping mechanism for the turbine is actuated. Otherwise, the conditions that exist for the aforementioned valve apply here as well (series 560 to 580).
