Title: In-line sleeve valve

Abstract: An improved in-line sleeve valve comprises a modular tubular port having a stationary plug concentrically supported therein and a reciprocating tubular sleeve arranged for sealing against the stationary plug. A resilient, flexible flange connects the tubular sleeve and the tubular port. The flange is sufficiently elastic to allow easy manual displacement of the sleeve from the tubular stationary plug in order to allow the flow of liquid, but is biased in a first direction so as to return the tubular sleeve to a position abutting the stationary plug upon release thereof.
