Zusammenfassung:	This disclosure describes an improved type of sphere launching valve for use in meter prover systems. It comprises a horizontal axis cylindrical shell with opposed openings at top and bottom for the entry and exit of a sphere. There is a rotor axially supported in bearings with means to rotate the rotor at least through an angle of 180 DEG . A sealing means is provided on the rotor so that an expansible tubular sealing element can be inflated by fluid pressure so as to seal between the rotor and the internal sealing surface of the housing or shell. In the preferred embodiment there are two parallel sealing means, these run in an axial direction and a circumferential direction so that they completely seal one of the two openings to the housing from the other. The rotor is shaped as a cup so that when the top of the cup is facing upward a sphere can be loaded into the cup shaped interior of the rotor. At a later time the rotor can be turned 180 DEG and the open top of the cup will point downward so that the sphere can fall through the bottom opening of the housing, down through the pipe, and into the circulating system and the meter prover loop.
