Abstract
A solenoid operated directional valve with a valve body provided with a bore that has axially spaced annuli, a mounted surface with ports arranged in a pattern of standard configuration, and ducts extending from the ports to the annuli to provide passageways for flow of fluid, and a spool mounted for movement axially in said bore for controlling flow of fluid through said passageways, the passageways being formed in a unique manner in said body so that a minimum pressure drop occurs in the fluid flowing through each passageway.
