    摘要： In a reducing valve assembly having a fluid inlet port and a fluid outlet port with a main valve for controlling flow between the inlet and outlet port, the main valve includes a main valve member which is actuated by an operating piston including a piston rod. In order to improve the flow characteristics of the assembly, a movable wall of the piston which transmits displacement through the piston rod to the valve member is connected with the piston rod by shaping the wall extending therebetween with a spherically curved configuration outwardly in a diametral direction from the piston rod.

    摘要： In a reducing valve assembly including a vapor-liquid separator, a valve casing, having therein a valve mechanism defining a valve orifice and defining inlet and outlet openings having the reducing valve mechanism interposed therebetween, is arranged with the valve casing extended below the reducing valve to define a sump chamber, the extended portion of the casing extending from a part thereof which surrounds the valve orifice. An annular partition is provided at the upper part of the sump chamber to form an annular space between the partition and the extended portion of the valve casing, the annular space being arranged to communicate with the inlet opening from above and with the sump chamber from below. Further, the annular partition is configured to define a central passage in flow communication between the sump chamber and a space below the valve orifice and a rotation deflector is arranged within the annular space and a drain valve or steam trap is arranged in the sump chamber to discharge liquid accumulated therein.
