ABSTRACT:
A sanitary milk inlet valve for a pipe line milker includes a two-part valve housing with the valve parts having laterally extending flanges which are secured together by bolts to clamp the valve housing at a selected position on a milk pipeline. One valve part encloses a rubber seal which partially surrounds the inlet pipe and which includes a rubber boss with a through aperture which seals the inlet pipe extending into the pipeline or manifold line. The inlet pipe is easily inserted and removed for cleaning purposes. The valve housing part which receives the inlet pipe also includes a spring biased cover which moves under force of a spring to a closed position to seal the inlet pipe opening when not in use. The cover also carries a neoprene rubber seal to seal the opening. When the inlet pipe is inserted in place the cover is displaced and a concave recess in the cover engages the inlet pipe and secures the pipe in place and provides a fluid seal.
