ABSTRACT:
A fluid control apparatus comprising a manifold and one or more valve assemblies adapted to be mounted on the manifold for controlling the flow of a pressure fluid. The manifold has a pair of main flow passages associated therewith, one being a supply passage and the other being a discharge or exhaust passage. A pair of load ports is provided in the manifold, and a set of openings is formed in one face of the manifold for cooperation with a valve assembly, which openings provide communication between the load ports and the main flow passages through the valve assembly. The openings in the manifold cooperate with further openings in the valve assembly so as to permit the valve assembly to be mounted on the manifold in a selected one of two different positions, in which positions the valve assembly cooperates with the same set of openings in the manifold but results in the valve assembly functioning as a normally open or a normally closed valve. The same set of manifold openings also permits a four-way valve assembly to be mounted on the manifold.
