Abstract
A valve apparatus is integrally molded from an elastomeric material so as to form a valve seating portion including a valve opening, a valve member and connective strands extending from the valve seating portion to the valve member. The valve member is initially molded on one side of the valve opening, and a portion of the valve member is passed through the opening to the other side thereof. The connective strands are stretched while passing a portion of the valve member through the opening so as to create a bias on the valve member which tends to seat the valve member on the other side of the opening.
