Abstract
A dual inlet ball valve for use in controlling the flow of gas to a log lighting device used in a fireplace comprises a valve body having a horizontal inlet connector, a vertical inlet connector, a outlet connector and a valve stem support structure. A horizontal inlet flow passageway extends through the horizontal inlet connector in horizontal alignment with an outlet flow passageway extending through the outlet connector. A vertical inlet flow passageway extends through the vertical inlet connector in vertical alignment with a stem receiving bore in the valve stem support structure. A ball having a bore hole extending therethrough is rotatably supported between the horizontal inlet flow passageway and the outlet flow passageway on valve seats in a ball support structure. A valve stem engaging the ball is operably engageable to rotate the ball from an open position to a closed position. A connecting flow passageway extending between a flared portion of the valve body wall and the ball support structure allows the vertical inlet flow passageway to flow communicate with the horizontal inlet flow passageway.
