Abstract (en)
[origin: WO8303644A1] A pilot operated flow control valve of a bypass type (13), which automatically regulates the quantity of flow delivered to the control orifice (14) to maintain a relatively constant pressure differential between the supply pressure (P1) and the load pressure (Pw) and which permits variation in the level of pressure differential ( DELTA Py) in response to an external control signal (71) while this pressure differential ( DELTA Py) is maintained constant at each controlled level.
