Claim 0:
1. A method to manufacture a valve apparatus comprising:
forming a valve body having an inner wall, a first portion of the inner wall, and a second portion of the inner wall, such that
the first portion of the inner wall defines an inlet port of the valve body,
a second portion of the inner wall defines an outlet port of the valve body, and
the inner wall, the inlet port, and the outlet port define a controllable flow path that extends along the inner wall between the inlet port and the outlet port of the valve body;

disposing an inlet gasket about the inlet port of the valve body, wherein the inlet gasket comprises a lip portion protruding from an inside surface of the inlet gasket;
disposing an outlet gasket about the outlet port of the valve body, wherein the outlet gasket comprises another lip portion protruding from an inside surface of the outlet gasket;
forming a rotatable member to include a substantially flat surface portion, an inner surface portion, and a tampered edge portion therebetween;
forming a seal ridge about a perimeter of the substantially flat surface portion of rotatable body such that the seal ridge contacts only the lip portion of the inlet gasket or the other lip portion of the outlet gasket during a transitional operation rather than an entire side surface of the seal ridge contacting the entire inside surfaces of the inlet gasket or the outlet gasket, thereby reducing friction between the seal ridge and the inlet gasket and the outlet gasket;
disposing the rotatable member in the controllable flow path of the valve body;
forming a shaft member to include a first portion and a second portion, wherein the shaft member is effective to actuate a position of the rotatable member such that the seal ridge is selectively engaged with either the inlet gasket or the outlet gasket; and
coupling the shaft member to the rotatable member by coupling the first portion of the shaft member to an upper portion of the rotatable body and the second portion of the shaft member to a lower portion of the rotatable body in an offset manner.
