Claim 10:
11. A valve comprising:
a valve housing including
a sidewall an open first end and an open second end that is opposite the first end,
a detachable lid that closes the first end of the sidewall,
a base that is disposed at the second end of the sidewall and is perpendicular to the sidewall, the base, the lid and the sidewall cooperating to define a chamber,
chamber walls that segregate the chamber into subchambers that each provide a portion of one or more fluid paths through the valve housing, and
valve ports, where each valve port
communicates with a subchamber, and
is provided in the base such that each valve port is an axially-extending through hole that resides in a plane that is common to all valve ports;

a diverter assembly disposed in the chamber, the diverter assembly configured to control fluid flow through the valve housing, the diverter assembly including a shaft that protrudes from the valve housing, the shaft being rotatable about a rotational axis that is parallel to the sidewall; and
a seal assembly disposed in the chamber so as to be aligned along the rotational axis with the diverter assembly,
wherein
the valve ports comprise a first valve port, a second valve port, a third valve port, a fourth valve port, a fifth valve port, a sixth valve port, a seventh valve port and an eighth valve port,
the chamber walls comprise an inner chamber wall that defines a first subchamber that includes the rotational axis,
the first valve port, the second valve port, the third valve port and the fourth valve port are each disposed in the first subchamber,
the fifth valve port is disposed in a second subchamber that is disposed radially outward with respect to the first subchamber,
the sixth valve port is disposed in a third subchamber that is disposed radially outward with respect to the first subchamber,
the seventh valve port is disposed in a fourth subchamber that is disposed radially outward with respect to the first subchamber,
the eighth valve port is disposed in a fifth subchamber that is disposed radially outward with respect to the first subchamber, and
the inner chamber wall segregates the first subchamber from each of the second subchamber, the third subchamber, the fourth subchamber and the fifth subchamber.
