Abstract
New valves to allow or prevent material flow through a conduit are disclosed. Such valves comprise a valve seat having a longitudinal axis, defining a through opening and including a seating surface which defines a portion of the through opening. A valve body, operatively coupled to the valve seat, is located at least partially in the through opening. A valve element is secured to and movable relative to the valve body. The valve element includes a sealing surface which is curved in at least one plane parallel to and including the longitudinal axis of the valve seat and is adapted to contact the seating surface to prevent material flow through the through opening. Pump assemblies and condiment dispensing systems employing such valves are also disclosed.
