ABSTRACT:
The invention relates to a disposable ball valve assembly mainly composed of a ball valve member made of a plastic resin material, a valve stem made of a plastic resin material and coupled with the ball valve member, and a valve body having a valve cavity formed therein for movably mounting the ball valve member. For improving the disposability, the valve body is substantially composed of a first body element made of a plastic resin material and having a portion thereof shaped to define a female connection, and a second body element made of a plastic resin material and having a portion thereof shaped to define a male connection inserted into the female connection. These first and second body elements are permanently coupled and rigidly interconnected to each other by these two connections with the end of the male connection being spaced from an interior portion of the first body element to define therebetween a valve chamber holding the ball valve member for the establishment of the disposability. These first and second body elements have non-threaded and inwardly reducedly stepped bores formed therein. The ball valve member is rotatable for fluid flow on-off control. Portions of these body elements define the valve chamber. The ball valve member, sealing ring means sealingly coacting therewith, the valve stem, O-ring(s) serving as sealing means between the valve stem and the valve body are positioned therein in an unseparable manner from the valve body for attaining the disposability.
