Application
The VB6 6-Way Control Ball Valves regulates hot
and chilled water with glycol solutions up to 60%
in heating, ventilating, and air conditioning
(HVAC) systems.
These valves ship with a direct coupled actuator
factory installed for modulating control. The valve
is designed to be used exclusively with
MN7510A2001 actuator.
Application Notes
IMPORTANT:

Valve sizing is important for correct system
operation. Undersized valves do not have suf-
ficient capacity at maximum load. Oversized
valves do not have sufficient authority over
the load in modulating applications.
Oversized valves can cause excessive cycling
and the seat and ball can be damaged because
of the restricted opening.
Proper Use
These valves are intended for use in chilled water
and hot water closed loop applications only, with
a media temperature range of 0 ºF to +212 ºF (18
ºC to 100 ºC), and static pressures up to 600 psi.
These valves are to be operated with the Honey-
well MN7510A2001 actuator only.
Water should be properly filtered, treated and
conditioned for good operating performance,
according to local conditions, and recommenda-
tions of the boiler or chiller manufacturers. The
installation of strainers and filters is recom-
mended.
IMPORTANT:

The presence of excessive iron oxide (red rust)
in the system voids the valve warranty.
Required Operating Torque
The VB6 series 6-way control ball valves are to be
operated with the Honeywell MN7510A2001
actuator only
These valves use a patented seat design that
reduces the torque needed. The nominal required
operating torque is 88 lb-in.
Table 1. Close off Pressure
Flow Characteristic
The VB6 series 6-way Ball Valves have true equal
percentage flow characteristic, thanks to preci-
sion machined metal discs in front of the ball.

Valve Sizing
Typical pressure drop across a control valve is in the range of 3 to 5 psid, however the best control is
achieved when the valve pressure drop is as close to the coil pressure drop as possible.
The 6-Way valve will have two CV calculations, one each for Sequence 1 and Sequence 2, which will
feature different flow rates most of the time.
INSTALLATION
When installing this product...
1. Read these instructions carefully. Failure to follow them could damage the product or cause a haz-
ardous condition.
2. Check ratings given in instructions and on the product to ensure the product is suitable for your
application.
3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out product operation as provided in these instructions.
Preparation
Caution: Equipment Damage Hazard
Foreign particles like dirt and metal chips can damage the ball seals.
For trouble-free operation of the product, good installation practice must include initial system
flushing, and chemical water treatment. Clean the lines upstream of particles larger than 1/16
inch diameter (welding slag, pipe scale, sand and other suspended particulate). Use of a 50
micron (or finer) system side stream filter is suggested. Remove all filters before flushing.
Do not use boiler additives, solder flux and wetted materials which are petroleum based or
contain mineral oil, hydrocarbons, or ethylene glycol acetate. Compounds which can be used,
with minimum 40% water dilution, are diethylene glycol, ethylene glycol, and propylene glycol
(antifreeze solutions).
If installing these valves in an addition to, or retrofitting an existing building, do not assume that
the fluid in the existing piping meets these criteria.

Mechanical Installation of the
Valve
IMPORTANT:
Hold valve with pipe wrench by hexagonal fit-
ting ONLY. Do NOT handle the Valve body with
the pipe wrench; product damage may result.
Refer Dimension section on page 9 for more
details on dimensions of Valve body and actuator.
1. Clean the lines upstream of particles larger
than 1/16 in. diameter (welding slag, pipe
scale and other contaminants) to properly
flush the system.
2. Proceed with installation once the system
specifics (expansion/contraction of the
system and its medium as well as operating
pressures) are within tolerances.
3. Eliminate air or air-bubbles from system.
4. Use the markings on the valve bodies to
familiarize yourself with the A, B, and AB
piping connections.
5. Connect the AB-ports of the valve to the
supply and return pipes of the coil.
6. Connect the A-ports and B-ports as per the
flow sequences. Refer to below figure.
Figure 1. Typical flow directions for Sequence 1 and 2.
IMPORTANT:
Strictly follow flow direction and port connec-
tions as per flow sequences.
7. Clear threads on both valve and piping of any
debris. Honeywell recommends Permabond
A1044 or equivalent thread or pipe sealant.
While using Teflon tape, it is recommended to
use 4-6 rounds of tape applied tightly in
clockwise rotation. When using hemp as pipe
sealant, ensure no strands are left in the valve
or piping.
8. Valves must be installed avoiding
unnecessary pull or twist in the valve housing.
9. Use the Bracket as shown below figure if non-
flexible pipes are used in piping to keep pipes
firm and parallel.

Electrical Installation
The most important part of the electrical installa-
tion is the power supply for the actuator.
1. Unscrew the actuator wiring cover in order to
access to the terminal block(s) as shown
below.
2. Perform the wiring of actuator using Figure
13 to Figure 15 as per the required
application.
3. If necessary, use the appropriate electrical
cable conduits and cable gland to properly
secure the actuator wiring.
4. Replace the wiring cover once done.
Actuator Run modes
The function selection switch (see Figure 16) can
be used to place the actuator into any one of two
different modes:
• Modulating run mode
• Floating/2-position run mode
• Service/Off mode.
Caution: To avoid personal injury
(electrical shock) and to prevent
equipment damage, before
installation, you must remove power.

Figure 16. Function Selection Switch

VB6 SERIES 6-WAY CONTROL BALL VALVES AND ACTUATORS - INSTALLATION INSTRUCTIONS
31-00380M-02 Printed in USA 8
Modulating Run Mode
The Modulating Run mode can be used in four different types of control settings:
• 2…10 Vdc
• 0…10 Vdc
• 10…0 Vdc
• 10…2 Vdc
If the function selection switch has been set to one of the four modulating control settings - and if the
actuator is wired correspondingly (see Figure 13) - then as soon as operating power is applied, the
shaft adapter will run first completely counterclockwise and then completely clockwise, after which it
will run according to the control signals applied.
Use the above flow curve with given actuator control signal settings to configure 6-way valve for
Sequence 1 (cooling), Sequence (2), and Off-position. Note that in Figure 13 it is shown how to over-
ride the actuator with a switch on wiring terminal 4 to go to the 50% position. This may also be used to
rotate the valve to the zero (closed) position.

IMPORTANT:

The zero (closed) position of the valve can be
achieved with control signal as shown in the
below table.
Floating/2-Position Run Mode
(Not recommended)
Using the MN7510A2001 actuator in floating /
2-position mode is not recommended with 6-way
valves. Both Sequence 1 and Sequence 2 are
closed at the actuator mid-stroke, 45 degree
actuator rotation. It must be possible to com-
mand the actuator to position itself in the mid-
stroke position, which is difficult to do with preci-
sion in floating mode, and impossible when float-
ing mode is used for 2-position control.
If it is desired to use the 6-way valve for simple
seasonal changeover service, it is best if three
distinct positions can be achieved:
1. Fully clockwise actuator rotation for
Sequence 2 to be fully open.
2. Fully counterclockwise actuator rotation for
Sequence 1 to be fully open.
3. Exactly mid-stroke, 45-degree actuator
rotation, for Sequence 1 and 2 both being
closed.
This scheme can only be achieved with the actu-
ator selector switch set to one of the four modu-
lating modes, using 0-10 Vdc, 2-10 Vdc, 10-0
Vdc, or 10-2 Vdc to achieve full clockwise, full
counterclockwise, and precisely mid-stroke actu-
ator positions. If desired, the actuator analog
feedback can be used to verify actual position.
If only step 1 and 2 above are desired, and there
is no need for step 3 to rotate the actuator to
exactly 45 degrees to turn both Sequence 1 and
2 completely off, the floating mode may be used
for 3-wire 2-position control.
Power-Off Behavior
If power is removed, the shaft adapter remains in
position.
Service/Off Mode
If the function selection switch is set to the “Ser-
vice/Off” position, then all rotary movement is
canceled, and all control signals are ignored,
allowing the actuator to be manually operated
safely. Press and hold the De-clutch button and
use the handle to operate the actuator to
Sequence 1, 2, or, Off positions.
Overriding
The MN7510A2001 can be overridden to the
50% position by applying a 24 V signal to termi-
nal 4 (see Figure 13.) With 24 V signal applied the
actuator will ignore the control signal at terminal
3 and instead drive to the 50% position closing
both Sequence 1 and Sequence 2.
Feedback
If correspondingly wired via terminal 5 (see Fig-
ure 13 to Figure 15), the actuator provides a
feedback signal proportional to the actual posi-
tion of the shaft adapter.
