<p>A pneumatic valve assembly (10, 110) including a valve body (12, 112) having an inlet port (30, 130) in fluid communication with a source of pressurized air and a valve bore (36, 136) extending axially within the valve body (12, 112) with a valve member (46, 146) movable between predetermined positions within the valve bore (36, 136). The valve member (46, 146) selectively movable to direct a flow of pressurized air from the inlet port (30, 130) through the valve bore (36, 136) to an outlet port (32, 132). A valve element (52, 152) is disposed upon the valve member (46, 146) having an angular valve sealing surface (62, 162), and a valve seat (82, 182) is defined in the valve bore (36, 136) formed at an oblique angle to provide a sealing contact with the valve sealing surface (62, 162) when the valve member (46, 146) is in a closed position thereby interrupting said flow of pressurized air.</p> |
