"PLUG VALVE" ABSTRACT A tapered plug valve containing a tapered plug surrounded by a sleeve of elatomeric material which deflects upon high fluid pressure applied through the valve inlet port, leakage which might otherwise occur due to such deflection being absorbed by 'O' ring seals. The plug may also be urged into the valve body by hydraulic pressure from the inlet port, and this maintains a sealing contact between the elastomeric material and the valve body surrounding the ports.
