Abstract

1370802 Valves R T BEAZLEY 23 Aug 1972 [9 June 1971] 19552/71 Heading F2V A valve for isolating fluid in a pipe in the event of fire has a closure member 3 mounted and retained in a cap 2 made wholly from a material which will deform and collapse at a lower temperature than the material of the valve casing. The cap may collapse at a temperature of, say, 300‹ C. while the casing and a cover nut 5 are made from cast iron or other metal to withstand a temperature greater than 800‹ C The valve may be closed by gravity or a spring 4
