ABSTRACT:
A pressure compensated load responsive flow control valve for use in a system controlling a plurality of loads. The system is powered by a single, fixed displacement pump. The flow control valve is equipped with a load responsive control, which during simultaneous control of multiple loads automatically maintains the pump discharge pressure at a level higher by a constant pressure differential than the pressure required by the largest load being controlled and which while system loads are not being controlled using external source of pressure fully opens pump bypass and reduces the pump bypass pressure to a minimum level.
