ABSTRACT:
A valve assembly having a single stem slidably supported within a bore formed in a one-piece valve body provided solely with four ports. The stem is hollow to permit the exhaust from two load ports to be directed into a single exhaust port. This single exhaust port can desirably be provided with a pair of flow controls to permit individualized control of the exhaust from each load port. The valve poppets are preferably axially press fit unto the valve stem, particularly on portions of the valve stem which are of slightly different diameters, to permit the individual poppets to be precisely axially positioned relative to one another and relative to the valve seats to achieve high tolerance and precision of operation.
