A valve device includes: a valve box in which an inlet flow passage into which steam flows and an outlet flow passage through which the steam flows are formed, and in which a valve chamber that connects the inlet flow passage and the outlet flow passage is formed; and a plurality of valve bodies configured to regulate a flow rate of the steam flowing through the outlet flow passage by relative movement to the outlet flow passage. The valve box includes a valve box main body in which the inlet flow passage, the outlet flow passage, and an opening portion are formed, a lid portion that is attachable to and detachable from the valve box main body and closes the opening portion, and a cleaning nozzle that is disposed to penetrate through the lid portion and is configured to supply a cleaning liquid into the valve chamber from the outside.

The present invention relates to a lever for adjusting an adjustable vane of a turbomachine, wherein the lever has a fulcrum for the rotatable mounting of the lever about an axis of rotation, a first load arm with a first adjusting connection point for at least indirect connection to an adjustable vane and a first force arm with a first actuating connection point for connection to an adjusting device, wherein the lever further has a first strut, which connects the first adjusting connection point and the first actuating connection point to each other and thereby extends in an arc-shaped manner about the axis of rotation.
