Abstract

905,717. Valves. AUDCO Ltd. June 10, 1960 [June 17, 1959], No. 20741/59. Class 135. A valve having components which slide over one another wherein the closure member, e.g. rotary plug 10, its seat or each of these components is formed of non-porous material, e.g. iron, stainless, carbon or alloy steel, nickel bronze or copper alloy and the sliding surface provided with a layer 12 of porous material similar to the non-porous material or different from it, e.g. a synthetic resin, formed by spraying, sintering, phosphating or other chemical treatment which forms a matrix absorbing part of a coating 13 of synthetic resin having non- seizing and sealing properties, e.g. polytetrafluoroethylene. Coating 13 in the form of a dispersion may be applied by dipping, spraying or vacuum impregnation followed by heating, and may be repeated several times. Alternatively, the coating may be formed from a tubular envelope.
