Abstract
A flow-control valve assembly particularly useful in fire fighting apparatus comprising a contoured valve seat mounted axially within a valve body and a balanced tubular valve member reciprocably movable in the valve body coaxially with said valve seat for providing proportional flow control, manual valve actuating means for reciprocably moving the tubular valve member including a disc rotatably mounted in a bore formed in a lateral surface of the valve body on a pivot member on which a handle is pivotally mounted and a pin spaced from the pivotal member extending through the handle and the disc which engages in a circumferential groove formed in the outer surface of the tubular valve member for effecting reciprocable movement of the valve member when the handle is reciprocably moved. The disc can be made of deformable material and provided with means for expanding the disc to impart a braking action on the movement of the handle. Also, the handle can be provided with detent means for conveniently positioning the valve member in a pre-selected position.
