Abstract
1305904 Valves L J LAFFAN 6 April 1970 [11 April 1969] 18739/69 Heading F2V Flow from an inlet 12a to an outlet 11a is controlled by a hemi-spherical or semi-cylindrical closure member 15 which has a uniform diameter and thickness, and which is rotatable by means of a spindle 14 between its two operative positions. In one of the operative positions a port 24 in the closure member is aligned with the inlet and outlet and co-operates with two annular sealing members 20 and 21 the former of which is carried by an inlet extension 19 and the latter of which is anchored between two of the three parts 10, 11 and 12 constituting the valve body. A clearance at the connection between the closure member 15 and the spindle 14 provides for possible seating of the closure member on an annular portion 10a of part 10 in the event of sealing member 21 failing.
