ABSTRACT:
A valve containing a central recess is rotatable in a housing 180.degree. in opposite directions to cause its recess to register selectively with identically shaped inlet and outlet ports that are formed in opposite ends, respectively, of the housing. One of a pair of circular end plates, which are secured over opposite ends, respectively, of the housing by a pair of conventional coupling members, has an axial bore that communicates at one end with the inlet port, and at its opposite end with an integral pipe that extends exteriorly of the housing, and which has an externally-threaded outer end that is adapted to be threaded into the outlet side of a conventional tee fitting, the run of which is connected in a pipe through which fluid flows under pressure. The other end plate contains a first opening connected to a drainage tube, and a second opening which is used as a vent for admitting atmospheric air to the outlet port. When the valve is turned to register with the inlet port it receives a sample of the fluid from the pipeline; and when rotated 180.degree. in the opposite direction the fluid in its recess drains by gravity out of the outlet port to the drainage tube. The coupling members can be releasably attached to either end of the housing, so that a mounting bracket, which projects from one side of the housing, can be made to project selectively from either side of the tee to which the housing is coupled.
