as well as other types. The valve 25 includes a
disk holder or valve member 96. The disk holder
housing formed of three sections designated gen
96 is ñxedly carried on -the stem and supports a
erally by the numerals 45, 46 and 56, the sections
45 ,and 46 being secured together byflanges 41
and 48 y and bolts 49 spaced annularly of the
flanges. The sections are thus secured together
to form a plurality of chambers or ,passageways
for the flow of liquid between the various con
duits connected to the valve. The section 45 has
a pipe connection 5| >for connection to the con
duit 33 leading to the top of the softener, a pipe
connection 52 connected to the, conduit 34 leading t
to the bottom of the softener, a pipe connection
at 534 connected to the service line 21, and a pipe
connection at 54 to which the raw Water supply
conduit 26 is connected. The valve section 45
has a flange 55 on the side thereof oppositev the
flange 41 to which the manifold member 56 is
attached by means of a flange 51, the manifold
member having an inner Wall 58 which serves
as one Wall of various chambers within the valve
casing. The manifold 56 has a pipe connection
59 to which the waste pipe or conduit 32 is con
nected, >communicating with a chamber 6| within
the manifold which forms part of the waste pipe
or conduit for conducting the waste water from '
the valve.
Y
The side of the section 46 opposed to the sec
tion 45 is provided with openings 62 and 63 across
which are disposed diaphragm members 64 and
65 secured-thereto by caps 66 and 61 and screws
68 spaced annularly of the caps, the caps being
disposed outwardly from the plane of the opening
tov form liquid chambers 69 and 1| for actuation
of the diaphragms to the right facing Fig. 3.
Conduits 12 and 13 communicate with the cham
bers 69 and 1| for the purpose of supplying pres
sure liquid for the actuation of the diaphragms,
as will presently be described.

Thesection 45 has a transverse partition 14
which joins a transverse partition 15 of section
disk 91 on one face for cooperation with the`
valve seat 88,` the disk 91 being formed of thick
resilient material such as'relatively soft rubber
in which the seat 88 will be impressed to produce
a seal therebetween.
In this instance the disk
91 is secured -against the disk holder by a ring 98
engaging the outer face of the disk. The oppo
site side of the disk holder 96 carries a disk 99
of thick resilient rubber secured thereto by means
of an annular ring andscrews |0|, the disk 99
being adapted to produce sealing contact with
the seat 92 in the opposed position of the stem.
Attached to thestem 9| adjacent the port 81
is a disk holder or valve member |02 having a
threaded bore for screw :thread engagement with
the threaded end of the stem as shown at |03.
Thedisk holder |02 likewise carries a disk |04
of thick soi-t and resilient rubber adapted to con
tact the seat 94 at the same ltime as the disk 99
contacts the seat 92. The disk holder |02 and
.the end of the stem 9| have such threaded en
gagement that by rotating the disk holder the
relative position of this disk holder with respect
to the holder 96 can be adjusted so as to cause
simultaneous seating of the disks 99 and |04.
The disk‘holder |02 is held in its adjusted posi
tion by means of .a cap |05 threaded over the
end of the stem so as to lock .the disk holder in
position and simultaneouslyV seal the disk holder
with respect to the stem so as to prevent'the
egress of liquid .therethrough under the operating
pressure of the valve. A removable plate |06 is
. provided on >the manifold 56 -to facilitate adjust
ment of the disk holder. As previously described,
fluid is admitted under pressure .through the tube
12 into >the chamber 69 in order to move the valve
disks 99 and |04 to ythe closed position as shown
in Fig. 3, whereas release of fluid from the cham

thus cause closing of the switch 244 (Fig. 18).
Upon closing of the switch 244, the motor 2|‘8A isA
again energized, shifting the rotor back tothe

various hydraulic valves tothe service position

as heretofore described, thus completing the cycle
of regeneration and return to service.

Simultaneously with movement of the rotor
from the position of Fig. 17 to that of Fig. 13,
the meter disk 205 is reset. This is accomplished
by means of a, cam face 299, in this instance posi

is attached to the end of the stem 249 and carries
a latch 321 pivoted thereon adapted for engage
