Installation and Operating 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.)

in Figure 2. The check valve will prevent water from
back-flowing into the mold after purging. Depending on
Supply Manifold
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
figure 2
recommended to bleed off residual air introduced by the
SWAP Valve. See figure 2. See figure 3 for installation
without air separator.
