In this article, the methodological principle of separation of functions in designs of gas and oil pipeline devices (gate valves, cocks, valves, fittings, etc.) is formulated for conditions of operation in polluted working media and the trends of application of this principle in design and technology are discussed. It is shown that this principle is most fully and usefully put into practice in design of highly reliable 1GR type of shutoff-control (multipurpose) valve protected by Russian Federation patent for invention. The critical nature of the problem of shutoff-control valve quality is proved by comparative analysis of the special features of modern designs of similar articles, which affect the important hydraulic characteristic of the flow section of the valves. In the proposed design of the IGR valve, the flaws revealed have been removed and its merits with respect to hydraulic resistance and flow characteristics, which fully correspond to the current requirements in the gas industry, have been shown theoretically.
