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.
