Condenser

1. Condensate Drainage Control Valve (Variant I)
This control valve regulates the level in the condenser and then directs the condensate back to the boiler feedwater tank or to a process line (Arca Ecotrol® Series 8C and 6N).

2. Condensate Circulation Control Valve (Variant I)
This control valve regulates the minimum quantity in the condensate pump to ensure that the pump does not run dry. The shaft / spindle seal for this control valve must be vacuum-tight so that it does not influence the underpressure in the condenser, especially during start-up (Arca Ecotrol® Series 8C).

3. Motive Steam Control Valve
Vacuum in the condenser is created using a steam-jet pump while the plant is started, when the turbine has not yet reached operating speed. Vacuum pressure is then adjusted by the motive steam control valve (Arca Ecotrol® Series 8C and 6H and Series 190).

4. 3-Way Distribution Valve (Variant II)
Circulation control for regulating condensate drainage can also be done using a 3-way diverting valve (Arca Series 200).
