Poppet valve having an improved valve seat

A pneumatic valve assembly comprising:

• a valve body having a pressurized air supply inlet port in fluid communication with a source of pressurized air;
• a valve bore extending axially within said valve body and a valve member movable between predetermined positions within said valve bore to selectively direct a flow of pressurized air from said inlet port through said valve bore to at least one outlet port;
• at least one valve element disposed upon said valve member, said at least one valve element being over-molded with a resilient material to provide an angular valve sealing surface;
• and
• at least one valve seat defined in said valve bore and formed at an angle oblique to said valve bore, said oblique angle measured relative to a radial line extending perpendicularly outward from the centerline of said valve member, such that said oblique angle is 2 to 3 degrees less than the corresponding angular measurement of said angular valve sealing surface, said valve sealing surface and said valve seat cooperating to form a surface seal such that said valve seat is in surface sealing contact with said valve sealing surface of said valve element when said valve member is in a closed position thereby interrupting said flow of pressurized air.
