摘要：
A valve body having a ring of dissimilar material and a method of forming the valve body are described. The valve body includes an inlet, an outlet and a ring of dissimilar material. The method includes forming a valve core, splitting the valve core, placing a metal ring of dissimilar material between two pieces of the valve core, casting a valve body around the valve core, and fusing the metal ring to the valve body.
