ABSTRACT:
A valve system includes a source of pressurized fluid comprising an orifice through which the pressurized fluid flows away from the source, and a poppet comprising a groove and a seal positioned in the groove, wherein the seal plugs the orifice when the poppet is in a closed position, and wherein the poppet and the seal move through the orifice against a flow of the pressurized fluid to allow the pressurized fluid to flow through the orifice and away from the source. The seal may include an O-ring.
