ABSTRACT:
The present invention provides a flanged ball valve device which can be connected, as an integrated compact unit, to a pump at the valve flange end of the device by means of an integral flange and to various types of piping systems at the pipe end of the device by means of a pipe connector attached to the integrated valve housing of the device. The integral flange of the device is compatible with a variety of different sized pump flanges by virtue of a plurality of slotted bolt holes present in the integral flange. The valve handle provided in the present invention for opening and closing the spherical valve ball valve of the device is preferably U-shaped, thereby allowing increased surface area for insulation material of relative thickness to be wrapped around the integrated valve housing without disturbing handle rotation or covering the handle from view.
