ABSTRACT:
A direction flow control valve for control of positive and negative loads operated by a single pilot valve stage, which automatically maintains a relatively constant pressure differential across valve spool, while controlling positive and negative loads and which permits variation in the level of pressure differential in response to an external control signal, while this pressure differential is maintained constant at each controlled level.
