Abstract: A two stage valve assembly (10) responsive to signals from a control system for supplying pressurized fluid to one of two load lines. The first stage (14) includes a torque motor that directs pressurized fluid from a jet pipe toward a receiver assembly having two receiver ports and a bleedoff area disposed between and separating the receiver ports. The second stage assembly includes two spool/sleeve assemblies (18, 20) that control the flow of pressurized fluid to and from the two load lines. The receiver assembly controls the spool/sleeve assemblies (18, 20) such that at most only one of the load lines is pressurized at a time. Cartridges may be inserted in the spool/sleeve assemblies (18, 20) to linearize the relationship between input current from the control system and the output force of an unequal area actuator (200) connected to the load lines.
