Abstract

802,266. Valves. LANGLEY ALLOYS, Ltd. May 11, 1956 [May 25, 1955], No. 15091/55. Class 135. In a screw-down gate valve, the gate 1, Figs. 1 and 2, has guiding lugs 22, 23 and at least one of the annular faces of the gate 1 has circular ribs which are of generally triangular cross-section and the tops of which are deformed by engagement with the associated seat. The gate may be of composite form. In another example, Fig. 7, the ribbed faces are formed on separate ring members 42 and seating rings 34, 35 are fitted to the valve body. The ribbed face or faces may be formed on one or both of the seats.
