ABSTRACT:
A valve interface provides a zero leak function for an area control valve. The valve interface is established by sealing contact between a concave valve face and a convex valve seat having mismatched radii. The concave valve face is formed on a valve element slidably disposed in a bore of a housing and the convex valve seat is formed in the housing and intersects with the bore.
