ABSTRACT:
A spring-loaded ball valve for controlling the flow of fluid therethrough. The ball valve includes a housing having a longitudinal conduit extending completely therethrough along its longitudinal axis for allowing fluid to flow therethrough. A ball headed member is positioned within the longitudinal conduit and includes an aperture extending completely through the ball headed member for controlling the flow of fluid through the longitudinal conduit. A stem portion is connected to the ball headed member and is coupled to a handle member for moving the ball headed member between an open position wherein the ball headed member aperture is generally aligned with the longitudinal conduit for allowing fluid to flow therethrough and a closed position wherein the ball headed member aperture is not aligned with the longitudinal conduit for preventing fluid from flowing therethrough. The handle member extends outwardly from the stem portion toward a first lateral side of the longitudinal conduit. A stop member is positioned on the first lateral side of the housing. An elongated mounting member is positioned on the second lateral side of the housing. The mounting member secures a biasing member to the housing such that it engages the stop member and the elongated handle for biasing the elongated handle towards the closed position.
