Abstract

1536837 Valves KAMYR VALVES Inc 5 April 1977 14428/77 Heading F2V A butterfly valve 10 comprises a body 12 having an annular metallic seat ring 15 and an eccentrically mounted metallic valve disc 18 comprising a conical angle transported disc, i.e. a frusto-cone in which face A is slid relative to face B so that the centre line joining faces A and B makes an angle a, of between 20 and 40 degrees, with respect to a line perpendicular to the faces A, B. This construction provides circular line contact between disc and seat providing fluid tight metal sealing. Details of construction are given within the Specification.
