Abstract
A valve having a valve closing member rotatably supported on one or more valve stems which are positionally infinitely adjustable is disclosed. The valve has a valve body defining a bore with an upper passageway extending from the bore. A valve stem extends coaxially through the passageway and rotatably supports the valve closing member in the bore. A cartridge is coaxially located within the passageway between the valve body and the stem. The cartridge captures the valve stem and engages the passageway via screw threads allowing for infinite positional adjustment. The cartridge also houses bearings for rotation of the stem and seals for sealing the passageway. The valve body may have a second passageway coaxially aligned with the first passageway in which a second valve stem is located. The second stem engages the passageway via screw threads allowing for infinite positional adjustment. The adjustable stems allow the valve closing member to remain perfectly centered within the bore for maximum valve operational life.
