Three-way proportional valve |
摘要 |
An electrohydraulic proportional valve wherein an electromagnetic force motor sends a mechanical signal to a pilot actuator which moves a main spool. The pilot actuator includes a pilot spool slidably received in a pilot sleeve. A feedback spool which is movable with the main spool has a camming surface against which the pilot sleeve rides. A load check valve is provided that isolates the load pressure from system pressure when desired.
