Abstract

A polymer seat for insertion into a seat pocket of a ball valve is disclosed. The annular piece polymer seat has an inner diameter, an outer diameter, a front face and a back face. The outer diameter has a chamfer thinning the annular piece toward the back face. The front face has a chamfered edge to support a ball of the ball valve. And, the back face defines a concave surface and/or a surface with a radius.
