This invention relates to @multiport valves. ‘ ‘
Multip'ort‘ valves "have heretofore been so- 'de‘»
signed and -'constructed thatlthe-stem plate was
lifted from'thelseatibefore-turning the same-to‘

eliminating wear-‘and tear on the seat or gasket

tio‘nto =another.-» In ‘some ‘cases the stem plate
was' adapted‘to'be-turned without lifting and it
would accordingly dragon the gasket or gaskets,
different installations.

It is,_ therefore, another-‘w

Referring ?rst brie?y to Figs. 1 and 2, the valve

numeral 20 designating the stator or body mem 60 as to break up the bed preparatory to the salt
ber of the valve on which a ‘cap or cover 2| is
wash ?ow and also wash out from the top of the
suitably secured, compressing a gasket 22 there
tank whatever sediment accumulated on the top
between to prevent leakage. ' The cover encloses
the rotor or stem plate‘ 23, and this stern plate
in its three operative positions-service, back-y
wash, and salt wash or brine-controls the flow
of water through the valve by providing a differ
ent system of communication between the various
parts in the body 20 in each of the three positions.
It should be understood that although the valve
is one especially designed for use in controlling
the ?ow of ?uids to and from a zeolite water
softener, the invention is not limited to that or
any other specific application but is applicable
of the bed during the softening operation. The
water leaving. the top of the softener re-enters
the valve through the communicating ports 29' v
and 39 and flows through the passage 42 and out
of the valve through communicating ports 31 and
30 to the drain. This ?ow is continued for a pre
determined time, su?icient to thoroughly cleanse
the bed and prepare it for the salt wash. During
this interval raw water may be by-passed to the
service system by virtue of the fact that the port
4| in the stem plate 23 registers with the port 32
and, hence, also with the port 28 communicating
to valves generally.

end of a stem 63~that ‘projects freely through a

hole 64 in a boss 65 provided in the stem plate
operating the multiport valve rotates the wheel
23. The head 62 of the valve is'housed within a
recess 66 in the bottom of the stem plate, so that
there is nothing projecting below the plane of
the stem plate that would come into contact with
the gasket rings and interfere with the free turn

68 in the boss 65 parallel to the hole '64, and
these ports as well as the end of the hole are

stem 48 to move downwardly to close the shut
off valve 56 and open the relief valve 6|.
It
should be clear that the Valve 56 when left in the
open. position shown in Fig. 1 can be set at a
higher or lower elevation by rotation of the wheel
