There are two types of holder valve in present use,the old style and the newstyle. The old style of valve isshown in Fig. 3, the new style in Fig. 4, (a) in each case beingan elevation, and (b) a section. The new style differs from theold in that the flanges F, F on the gland G are dispensed with,the gland being made hexagonal at H and tightened up bymeans of a wrench, instead of using bolts, as in the old type. 6. Description of Parts.—The valve marked v controlsthe flow of gas into or out of the holder. To open or shut thisvalve, the cap C has to be taken off by means of key K, andthe valve turned by key Jc. g, g are gaskets to make the variousjoints gas-tight. The dotted circle behind the valve v is thepassage leading to the filler, the pipe connection being madeby the union u shown in the elevation. There is one of theseconnections on each side of the valve, as seen in Fig. 1. Theconnection to the holder is made by means of the outletbushing
