3.3.2 CONTROL VALVES WITH ACTUATOR
The purpose of the valves is to control the steam flow to the nozzle groups and thus also the turbine output.
The HP control valves are of double-seat types and are operated by one actuator.
Each control valve controls the steam flow to one nozzle group. The valves open gradually, i.e. the following valve opens when the maximum flow has been reached through the previous valve. By this flow control, a good efficiency is achieved even in the case of a partial load, because the loss by throttling is decreased.
Design description:
""Double-beat"" valves are used, in particular, for their symmetrical construction and, therefore, only a small operating force is necessary to operate them.

Ik doe een gok. Het kan een typo zijn (zie Lianne), maar aangezien het nog steeds om jouw "stoommachine" gaat, zou het zo maar mogelijk kunnen zijn, het past wel. (Dit keer helaas niets in mijn TM)

I wonder if there might be any confusion:
Zo klep kan zijn een 1zittingklep, waar dan de volle stoomdruk op de klep staat, zodat de opening nog al kracht kost, wordt deze altijd uitgevoerd als dubbel zittingklep zogenaamde evenwichtsklep zoals fig.127 aangeeft.
