ABSTRACT:
A check valve for a fluid line which can be easily disassembled and assembled for cleaning, inspection, or repair. The valve finds particular utility in cleaning-in-place equipment such as dairy pipe lines and in which the valves and other components must be quickly, easily, and completely disassembled for thorough cleaning at frequent invervals. The valve includes identical end sections which are formed of resilient material such as plastic or the like and which can be snapped on a central valve element guide and also easily disassembled therefrom. A shiftable valve element is located on the central valve guide and can also be easily disassembled therefrom for frequent and thorough cleaning. The width of the central guide is such that the valve element which is also of resilient material, is properly tensioned to insure its accurate location.
