Referring to the sectional view of the valve, it will be seenthat it is of the piston type, similar to existing Gold end. End Valve with Automatic Condensation Drip Port valves. In this case the piston is double seated with a com-position .seat at each end. When the valve is closed, piston Bis forced to the right by the cam on spindle //. therebyautomatically opening the drip-port. When the valve is inthe open position, the piston is forced to the left, the seaton this end forming a tight joint which automatically closesthe drip-port. A quarter turn fully opens or closes the valve,and it cannot be jarred from its set position by the vibrationof train, or unseated In the steam pressure. In the dri])-port is provided an adjusting screw G for varying theopening. lhe valve is substantially built, the body of iron andthe cam and spindle cast in one piece. The spindle is shortand of large diameter and should kee|) in perfect alinement for years. The area of the passage through it is so largethat it offers less resistance to the tlow of steam than the trainline itself. The seats of the valve are renewable and c
