Abstract:
1. A process for manufacturing a valve, comprising: casting a valve body without machining, wherein the valve body includes a conical cavity formed in the valve body, wherein an opening in a side of the conical cavity is in fluid communication with an exterior of the valve body and an opening in a base of the conical cavity is in fluid communication with the exterior of the valve body; molding a plug element without machining, wherein the plug element is configured and dimensioned for rotatable receipt within the conical cavity for the valve body, wherein the molding of the plug element further includes forming an orifice in a side of the plug element that is alignable with the opening in a side of the conical cavity for the valve body and in fluid communication therewith and the orifice in a side of the plug element is alignable with an opening in a narrow end of the plug element and in fluid communication therewith; overmolding pliable material without machining, having a plurality of sealing ridges protruding therefrom, wherein at least one sealing ridge of the plurality of sealing ridges extends circumferentially about the plug element above the orifice in the side of the plug element and at least one sealing ridge of the plurality of sealing ridges extends circumferentially about the plug element below the orifice in the side of the plug element and at least two sealing ridges of the plurality of sealing ridges extend between the circumferentially oriented sealing ridges with at least one sealing ridge on each side of the orifice in the side of the plug element; and positioning a biasing mechanism between the plug element and the conical cavity for the cast valve body, whereby an effective seal is achieved between the plurality of sealing ridges and the unmachined surface of the opening in the side of the conical cavity for the valve body.
