ABSTRACT:
A gate valve assembly is provided which includes a valve body having a fluid passage extending laterally therethrough which has an inlet end and an outlet end, with means at the inlet end and at the outlet end to connect the valve body to a fluid conveying conduit. The passage has a bottom surface coplanar with the bottom of the conduit and is free of recesses capable of preventing the drainage of liquids. An axially extending valve chamber intersects the passage and is disposed perpendicularly to the axis of the passage, the chamber having an elliptical cross-section with its widest dimension perpendicular to the passage. An axially and non-rotationally movable valve member is fitted closely within the chamber and has an internal, downwardly tapered hard, core member formed of metal, glass ceramic or hard plastic material. The core is surrounded by an elastomeric elliptically cross-sectioned outer member. The elastomeric member has a generally flattened bottom surface adapted to engage the bottom of the passage and is dimensioned to close the passage when extended into the closed position.
