<p>A pneumatic valve assembly including a valve body having an inlet port in fluid communication with a source of pressurized air and a valve bore extending axially within the valve body with a valve member movable between predetermined positions within the valve bore. The valve member selectively movable to direct a flow of pressurized air from the inlet port through the valve bore to an outlet port. A valve element is disposed upon the valve member having an angular valve sealing surface, and a valve seat is defined in the valve bore formed at an oblique angle to provide a sealing contact with the valve sealing surface when the valve member is in a closed position thereby interrupting said flow of pressurized air.</p> |
