Installation and perating Instructions
Applies to: SPV8-A-M and SPV8-L-M
General
The Smartflow SWAP Valve is a simple, manually
selectable device that supplies cooling water to the
mold during processing or air to purge the water
from the mold before a mold change.
The SWAP valve has three positions: WATER,
PURGE and VENT. The WATER position is
selected for normal processing. The PURGE
position is selected to evacuate the water before
mold change. The VENT position is selected to
bleed-off trapped pressure and drain residual water
before a mold change.
An optional spring-loaded locking pin is available
to prevent accidental movement of the valve
handle.
Assembly (as required)
1. Apply thread locking compound (Loctite 638 or
equivalent) to threaded end of valve handle.
Screw valve handle into center disk threaded
hole. See figure 1.
3. Thread manual vent into the hole as shown in
figure 1. (No additional thread sealant is
required. Do not over-tighten.)

Installation
The SWAP valve should be mounted to a suitable
surface using the mounting holes.
Line mounting to rigid water pipe instead of
bracket mounting is discouraged.
Connect water supply to the Water Inlet.
Connect shop air to the 3/8-inch NPT(F) Air Inlet with
either a permanent or quick-connect fitting.
Connect the Air/Water utlet to the cooling water
Supply manifold.
Install the check valve (included) in the return water line
downstream from the Return water manifold as shown
in Figure 2. The check valve will prevent water from
back-flowing into the mold after purging. Depending on
your installation, it may be desirable to add a check
valve to the air inlet ahead of the SWAP Valve.
In closed loop systems air separator installation is
recommended to bleed off residual air introduced by the
SWAP Valve. See figure 2. See figure 3 for installation
without air separator.

Using a Smartflow Mold Tem erature Regulator (MTR)
1. Stop the press.
2. Note the setting on the calibration scale, then move the knob to the “Flush” position (Clockwise to
the stop).
3. Perform the SWAP Purge Procedure (see PERATI N above).
4. n the MTR, return the knob on the calibration scale to the previous position. (It will be necessary to
rotate the knob more than one complete turn counterclockwise.)
5. Select Water after the new mold is installed and the cooling water connections are secure.
Using a TCU (temperature control unit in a closed loop system)
We recommend using a temporary bypass hose or TAC Air Separator per figures 2 & 3. Install bypass
hose and open ball valves on each end of the bypass before purging the mold (figure 3). An air
separator may be installed in the location shown at the highest point possible (figure 2).Your
installation may vary.
1. Stop the press.
2. Check the TCU manufacturer’s instruction for Purge position or Bypass instructions.
3. Perform the SWAP Purge Procedure (see PERATI N above).
4. Reset the TCU to the original operating configuration.
5. Select Water after the new mold is installed and the cooling water connections are secure.
Note: It is possible for the majority of the pur e air to rush throu h the unrestricted water
passa es, leavin some water in bubblers or baffles. After unrestricted mold passa es have been
pur ed, close valves on these passa es so more air is available to pur e the restricted water
passa es. It may be necessary to pur e lon er or to pur e restricted passa es individually to
completely evacuate the water.
Ca tion: confirm that the SWAP valve is selected to VENT and that the man al vent b tton has
been pressed to relieve trapped air press re or resid al water before disconnecting any water
lines. A drain t be can be connected to the Man al Vent-Drain and r n to a s itable drain.

Troubleshooting
Symptom
Air or water does not flow through the system
Corrective Action
• Verify check valve direction
• Check that the valve handle is in the correct
position
Water leaks from the valve while in operation • Replace -Rings
(Contact factory for repair or field replacement
procedure)
Mold does not evacuate completely • Check air pressure (80 to 125 psi required)
