up as shown in
Figure 16
. Doing so will allow water and
debris to collect in the cup where the wiring exits the
actuator, potentially causing damage.
Three-Way Valve Ball Orientation
The ball orientation must be verified prior to mounting the
flanged valve into the piping system. With the flanged four-
inch valve it is a fairly simple procedure. Do not use the
groove on the end of the drive linkage to verify.
First, remove the actuator by removing the wing-nut
underneath the mount bracket near the tail. Second,
loosen the locking bolt on top of the actuator that clamps
to the drive linkage.
Once this has been done, remove the actuator by lifting
straight off the drive linkage shaft.
Now the ball position must be verified. Using pliers,
grasp the base of the drive linkage. While looking into
port AB, rotate the drive linkage counterclockwise about
45 degrees. See
Figure 18
. You should see two partial
openings similar to
Figure 14
.
Figure 18. Rotating the Drive Linkage
If you do not see the two partial openings after 45 degrees
of rotation, continue rotating until you do. Once you see
the two partial openings, STOP. Now rotate the shaft in
the reverse direction (clockwise) until you can see straight
through to valve from port AB to port A.
Reinstall the actuator and bracket assembly in reverse
order, and ensure that the ball assembly is properly
oriented. Mount the flanged valve into your piping system
in accordance with this manual.
Valve Installation
To properly install this valve, port “AB” must be connected
to the combined outlet of the heater(s); and port “B” must
be attached to the bypass between the combined inlet and
the combined outlet, as shown on page 18. The valve
body has the port designators cast into the drive linkage
housing. See
Figure 19
.
PORT AB
Figure 19. Valve Orientation
4-Inch Valve Orientation
The valve must be installed so that the combined boiler
outlets enter through Port “AB” (See
Figure 20
). Port “B” is
the bypass port and port “A” is the return to the system (port
designations are cast into the stem of the valve body). The
valve body should be installed so that the actuator input
shaft is in the vertical or horizontal position. The Actuator
stem should never be hanging downward.
As shipped from the factory, the actuator is in the horizontal
position when the valve is installed as shown in
Figure
20
. The actuator position can be changed to suit jobsite
conditions.

Figure 20. Valve Orientation (Actuator)
Under no circumstances should the actuator be positioned
such that the electrical connection is pointing upwards
(see
Figure 16
) as this can allow for moisture or debris to
enter the actuator assembly and potentially damage the
actuator.
Before installing into the piping system, verify the valve
is positioned properly by referring to
Figure 20
and the
diagram "Typical Cold Water Start Multiple Boiler Piping"
on page 18.
