GENERAL DESCRIPTION FOR GATE, GLOBE & CHECK VALVES :


Body flanges of valves are drilled as per ANSI B-16-5/B.S. 1560 / DIN or alternatively drilled to B.S. 10 tables. Serrated raised face, ring-joint flange ends and butt-welded flange ends are available as per your requirements. KOR Valves are designed for smooth flow and suitable service. They are most preferred in modern industrial and petro-chemical plants as well as refineries.
