ABSTRACT:
A disconnect valve assembly is used to connect a source of fluid with a container to be filled. The valve assembly includes a tubular body having a fluid passageway extending therethrough from an inlet to an outlet. A depressor is located in the passageway intermediate the inlet and the outlet. A ball-valve check assembly is located in the passageway between the inlet and the depressor. This assembly includes a stem body slidably mounted within the passageway. The stem body has a stem passageway extending therethrough including a first passageway portion and a second passageway portion located downstream from the first passageway portion and being of smaller diameter than the first passageway portion. A valve seat interconnects the two portions. A resilient ball member is located in the first passageway portion and a spring serves to normally bias the ball member against the valve seat to prevent passage of fluid therethrough. A depressor is carried by the stem body in a telescoping arrangement therewith. The depressor carries an actuator rod that extends into the stem body for engaging the ball in the ball-valve check assembly. The depressor has a skirt portion having an annular flange which extends radially outward therefrom.
