Fluid flow control assembly

A device, comprising:

• a pilot valve device responsive to a command signal for supplying a fluid at a command pressure to a pilot valve control port;
• and
• a pilot operated spool valve having:
• a body having a first connector and a second connector, each of said first connector and second connector being adapted for fluid communication with an external circuit;
• and
• a spool disposed for sliding movement in said body, said spool having a first end portion and a second end portion opposite said first end portion, said first end portion of said spool being in fluid communication with said pilot valve control port such that said spool is urged to move in a first direction by said fluid at said command pressure, said spool being movable through a first range of positions to control, proportionally to said command pressure, the flow of a fluid when the fluid is flowing through said body in a forward direction from said first connector to said second connector, said spool being movable through a second range of positions, offset from said first range of positions, to control, proportionally to said command pressure, the flow of the fluid when the fluid is flowing through said body in a reverse direction from said second connector to said first connector, a portion of said fluid flowing through said body having a feedback pressure and acting on said spool in a second direction, opposite said first direction, to position said spool in conjunction with said fluid at said command pressure, the magnitude of said feedback pressure being generated at least in part as a function of the position of said spool.
