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 automatically reduces the pump bypass pressure to a minimum level lower than the constant pressure differential of the load responsive control.
