Introduction
The high pressure pump recirculation is one of the most difficult issues and severe duty control valve installations are demanded by the power industry. There are two significant features in this respect. First, the flow must be controlled during a very high pressure drop and second, when not in the controlling flow mode, a tight leak proof shut off is required. Failure to achieve either of these functions will quickly result in a plant shutdown or the loss of the valuable energy ov
