Abstract
Abstract A gate valve structure comprising a valve body defining a valve chamber and having inlet and outlet passageways disposed in fluid communication with the valve chamber. Internal bosses surrounding the inlet and outlet passages, protrude into the valve chamber and are provided with substantially planar sealing surfaces. A bonnet, forming a closure for the valve body, includes a reciprocating stem means for opening and closing the valve and supports a seat carrier and gate guide member which depends into the valve chamber. A pair of seat members are supported by the carrier for sealing engagement with the sealing surfaces and are disposed in sealing engagement with a gate member which is movably disposed within the carrier and connected at the upper extremity thereof to the valve stem. Upon separation of the bonnet from the valve body, the gate, gate guide and seat members are simultaneously withdrawn from the valve body as a unit, thereby promoting simple and quick replacement of all of the moving parts of the valve.
