Claim 4:
5. A valve assembly comprising:
a valve body having an inner wall, a first portion of the inner wall, and a second portion of the inner wall, wherein
the first portion of the inner wall defines a first port of the valve body,
a second portion of the inner wall defines a second port of the valve body, and
the inner wall, the first port, and the second port define a controllable flow path that extends along the inner wall between the first port and the second port of the valve body;

a first shaped gasket disposed about the first port of the valve body and comprising a lip portion protruding from an inside surface of the first shaped gasket;
a rotatable member disposed in the controllable flow path of the valve body, wherein the rotatable member includes an outer surface portion with a seal ridge formed about a perimeter of the outer surface portion such that the seal ridge contacts only the lip portion of the first shaped gasket during a transitional operation rather than an entire side surface of the seal ridge contacting the entire inside surface of the first shaped gasket, thereby reducing friction between the seal ridge and the first shaped gasket; and
a shaft member coupled to the rotatable member, wherein the shaft member is configured to actuate a position of the rotatable member such that the seal ridge is selectively engaged with the first shaped gasket.
