ABSTRACT:
A valve for regulating a flow of pressurized gas in a torch includes a valve body having a central bore and a connected outlet bore for passage of gas from a source to a torch tube. A valve needle is disposed in the central bore and is movable to open and close the central bore from the outlet bore. A valve seat is formed in a portion of the central bore and an end face of the valve needle faces the valve seat. A bonded elastomer seal is loosely disposed between the end face and the valve seat. When the valve needle is in the closed position, the end face compresses the bonded elastomer seal on the valve seat which closes the central bore from the outlet bore.
