  • Check valve including molded valve seat
    Patent number: 5749394
    Abstract: A ball check valve including a housing and a ball element movably positioned in the housing. An insert member is located at an inlet port of the housing, and an elastomeric element is molded directly onto the insert member and is positioned facing toward an outlet port of the housing for engagement with the ball element. A ball seat is ground into the elastomeric element at a precise angle matching a tangential angle of contact with the ball element such that engagement of the ball element with the ball seat forms a seal preventing fluid flow from the outlet port through the inlet port.
