Abstract
1307558 Valves DEMAG AG 24 Sept 1970 [1 Oct 1969] 45541/70 Heading F2V [Also in Division F4] A valve construction for a furnace, comprises a ring flange 2 defining a valve seat offset from the flow path of the charging material, and a valve member 6 having outer and inner portions 8, 7 respectively of different cross-section; the inner portion 7 having a cross-section such that it is more flexible than the outer portion. In a preferred embodiment, a groove 12 extends around the valve seat, inert gas being fed through an inlet 18 into the groove 12 to remove dust on the valve member 6.
