ABSTRACT:
A reduced length bolted ball valve assembly used to control the flow of liquid between components of a liquid handling system. The valve assembly includes an abutting pair of end bodies, connectable to the liquid handling system components, which are attached by bolts passing through flanges provided at the inward ends of the end bodies. One end body, which is provided with a liquid system connector that both outwardly projects from the attachment flange and is used to connect to the liquid handling system component, includes an interior cavity outward of its attachment flange. Housed within this interior cavity is a rotatable ball valve element with a diametric bore. A handle is engaged with the rotatable ball valve element via a member which extends through an end body bore, which opens into the interior cavity and which is located outward of the attachment flange. The handle allows the valve element to be rotated to effect opening and closing of flow communication between liquid conveying bores provided within the end bodies.
