<p>A steam valve assembly (21) has a main-steam stop valve (1), and a steam control valve (2) connected downstream to the main-steam stop valve (1) via an intermediate flow path (30). The two valves (1, 2) each has a casing (31, 41) having an inlet port (33, 43) directing horizontally, and an outlet port (34, 44) directing vertically. The valve bodies (32, 42) and the valve stems (37, 47) move up and down in the casings (31, 41) to open and close the flow paths in the valves (1, 2). The intermediate flow path (30) is configured to guide main steam from the outlet port (34) of the main-steam stop valve (1) in vertically downward direction to the inlet port (42) of the steam control valve (2) in horizontal direction.</p> |
