A second stage hydraulic valve is provided which has a valve body with a spool reciprocally movable in a bore. A first end of the bore is coupled to the aforesaid pilot outlet port. A spring abutment is provided in the bore at a second end remote from the first end, and a spring is oriented between and abuts the spring abutment and one end of the spool remote from the pilot outlet port for urging the spool to oppose the pressurized hydraulic fluid at the pilot outlet port.
