ABSTRACT:
A valve assembly having a single stem slidably supported within a bore formed in a one-piece valve body provided with three ports which communicate with the bore at axially spaced locations therealong. The axially centermost port functions as a load port. The valve stem has a single valve poppet mounted thereon in encircling relationship thereto, which valve poppet is axially movable between a pair of opposed valve seats formed on the valve body for controlling communication between the load port and the bore. The stem has a passageway extending axially therethrough to maintain a balanced pressure axially of the valve stem.
