Abstract (en)

[origin: ES8103324A1] The steam throttle valve has water injection ducts disposed about the valve axis. The ducts are situated between two abutting flanges of a valve cage and a valve spindle guide. The ducts are in the form of grooves in the flange while the adjacent peripheral surface of the flange is plain. The valve cage forms a replaceable wearing component and the configuration of the water injection ducts avoids thermal stress cracks in the duct zone.
