1. A valve assembly comprising:

  • a valve body formed of at least two body sections with two body sections having an elongate tubular passageway portion which at least partially define a ball cavity therebetween communicating with two tubular passage portions, wherein one of the body sections defines an auxiliary inlet/outlet communicating with the ball cavity and further defining a tubular spindle flange communicating with the ball cavity;

    an elongate spindle sealingly mounted within the spindle flange for limited rotation between an open position and a bypass position, the spindle having a first end extending toward the ball cavity and a second end external from the ball cavity;

    a ball valve oriented within the ball cavity and cooperating with the elongate spindle to be rotated thereby between an open position and a bypass position, the ball valve having a primary elongate passageway which extends therethrough to interconnect the tubular passageway portions of the valve body sections when the ball valve is oriented in the open position, the ball valve having an internal bypass port aligned with one of the tubular passageway portions in a valve body section when the ball valve is oriented in the bypass position, internal bypass port serving to interconnect one of the tubular passage portions in a valve body section and the auxiliary inlet/outlet.
