Abstract
Abstract A valve having a modular, multi-passage manifold or body. Different types of valve mechanisms are insertable axially through an open end of a cavity formed within the manifold and are sealed therein by a closure. Fluid connections for the valve mechanisms are provided by a plurality of passages which extend parallel to the cavity but within the wall of the manifold, from a common end of the manifold. Each passage extends longitudinally in the manifold parallel to the cavity over substantially all of the effective length of the cavity, and is selectively ported to the cavity at one or more positions along its length to serve the particular valve mechanism with which the manifold is used. The valve mechanism has circumferential grooves with which the respective manifold cavity ports communicate.
