Abstract
A directional control valve has a supply port, first output ports and discharge ports which are open at a lower surface of a valve body at positions for communication with corresponding openings in a manifold base. The lower surface of the valve body has attachments for attaching a blanking plate which can close all the above ports. The valve body has a supply passage and discharge passages defined therethrough in the direction in which directional control valves are arrayed, and held in communication with the corresponding ports. Second output ports are defined in an upper surface of the valve body in communication with the first output ports. With the blanking plate detached from or attached to the same valve body, directional control valves may be arrayed through the manifold base or directly on a rail.
