Abstract
The invention contemplates a particular body construction and assembly for a check valve or the like whereby the entire valve assembly may be readily installed as a unit within the bore of standard pipe or conduit, or a standard fitting therefor. A single circumferentially extending radially inwardly open groove in the bore of the pipe, conduit or fitting, faces a corresponding radially outwardly open groove in the valve body, and stiffly compliant circumferentially extensive retainer element such as a wire of suitable gage substantially fills these grooves to retain the inserted valve in place. The retainer element is adapted for ready removability, to enable servicing or removal of the inserted valve, and the valve body is so externally characterized as to unambiguously assure valve installation in the correct direction of desired flow.
