Compact integrated flanged isolator ball valve
First Claim
1. A flanged ball valve device for connecting pump devices to pipe systems comprising:
- a valve housing having a pipe end, a flange end, and an integral stem opening in the valve housing in between the pipe end and the flange end;
a flange on the flange end of the valve housing wherein the flange is an integrally formed part of the valve housing, the flange having two radially slotted openings capable of connection with a plurality of differently spaced attachment openings on connecting pump devices;
a spherical ball valve member within said valve housing, the spherical ball valve member having a central bore and being capable of moving to an open or closed position, thereby allowing or blocking passage of fluid through the spherical ball valve member;
a valve stem coupled to the spherical ball valve member and extending out of the valve housing through the stem opening;
a valve handle coupled to the valve stem for rotating the spherical ball valve member into an open or closed position.

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.
