An inventive priority flow regulator comprises a valve assembly which is supported by a housing at one end and confines an electro-magnetic actuator at the other end. The housing has an inlet port, an outlet port, and a regulated port. The valve assembly includes a hollow cage that cooperates with a cavity formed in the housing to define a plurality of internal chambers, a hollow compensating spool slidably arranged within the cage between rows of cross-sectional holes formed in the cage, a hollow guide member slidably arranged within the compensating spool and having cross-holes formed therein, and regulating and dampening spools slidably arranged within the guide member at opposite ends thereof. The internal chambers of the housing communicate with respective ports formed in the housing to provide a priority flow configuration as well as a reverse flow configuration.
