Subject: 464 Flow Control Base Kit (5031061)
This kit was developed to replace, and correct leaking flow controls on the 454 and
464 series valves. Please follow these instructions for installation of this kit.
Steps for Replacement:
1 Turn power off to valves by turning key switch to the off position.
2 Remove the cover from leaking valve.
3 Unplug the low voltage connection from valve. (See Figure 1)
4 Turn water and syrup off by turning the valve shutoffs on the Back Block to the off
position. (See Figure 2)
5 Remove the valve from unit by pulling the Latch pin up then pulling the valve toward
you. (See Figure 3)
Once the valve is removed from the unit all valve components must be removed from the
existing flow control base. Save all components removed from valve for reassembly unless
otherwise noted.
6 Remove the four screws from the front of the valve that secure the Diffuser block and
the Solenoid Coil Assembly. (See Figure 4)
7 Remove the Diffuser block and Solenoid Coil Assembly from valve.
8 Remove the two screws that secure the Pallet Retainer Spring and/or Orifice caps to the
flow control base. (See Figure 5)
9 Remove the Pallet Retainer Spring (if used), both Orifice Caps, and Pallets from the flow
control base. (See Figure 6)
10 Remove the Pivot Pin, and Coil spring (if used) from Flow Control Base. (See Figure 7)

11 Next remove the three screws that secure the retainer plate to the flow control base, and
then remove the retainer plate. Discard screws and retainer plate. (See figure 8)
12 Remove both Brix Nut assemblies (water & syrup) and discard. (See Figure 9)
13 Next remove both Brix adjustment springs. Make note which spring is for water and
which is for syrup.
14 Remove both ceramic Pistons (water & syrup) from the flow control base. Remove both
ceramic Cylinders from the flow control base. Make note which is for water and which is
for syrup. (See Figure 10)
15 Discard the original Flow Control Base.
16 Remove the 0-ring from each of the ceramic Cylinders and discard o-rings.
17 Install the sleeve 0-rings (5028273) included in kit onto each ceramic Cylinder.
(See Figure 11)
18 Insert the ceramic Cylinders into the new Flow Control Base (60047G), supplied in kit.
19 Insert the ceramic Pistons (removed in step 13) into the ceramic Cylinders. Note: Be
sure to install syrup piston (smaller orifice) on the syrup side, and the water piston
(larger orifice) on the water side.
20 Place the Flow Control Springs in the ceramic Pistons. (See Figure 12)
NOTE: 464-HF valves only. The spring for the syrup side of the flow control base
will have less coils than the spring for the water side of the flow control base.
21 Insert the two Brix Adjustment Nuts (64300) supplied in kit into the flow control base.
(See Figure 13)
22 Next install the Retainer Plate (61004) supplied in kit and secure with the three screws
(020001284) also supplied in kit.
23 Reassemble the balance of the valve following Step 2 - 9 in reverse order.
24 Once the valve is reassembled and installed on the dispenser secure valve by pushing
Latch Pin down.
25 Turn both Back Block shutoffs to the on position, plug valve in and reapply power to
valves by turning the key switch on.
26 Set the flow rate and brix ratio according to the syrup manufactures specifications.
