KNX Hydronic Hook-up Kit Solution
Armstrong balancing solutions provide leading valve technology for faster and more accurate balancing of fluid flow
in HVAC and hot water recirculation systems. Accurate circuit balancing assures design flows are available through-
out the system, as required for optimum system performance, energy efficiency and overall occupant comfort.

MS Series Mini-Sweat Valves
Armstrong Mini-Sweat valves are ideal for applications where compact circuit balancing valves (CBVs) are
required, such as in hydronic baseboard radiators or terminal unit panels. Available for
1

2
or
3
/
4
inch (13 to 19
mm) sweat pipe connections, these economical valves provide 360 degrees of flow regulation adjustment;
four times the precision of a 1/4 turn ball valve. After flow adjustment and system balance verification, the
handle can be locked in place to avoid loss of system balance by unauthorized adjustment.
f
ARMflo Series Venturi Based Valves
Armstrong Venturi based CBVs are needed for large commercial buildings where a small error in flow
measurement through a large number of terminal units can add up to significant energy waste for the life
of the system. These models provide ±5% flow measurement accuracy over the entire operating range,
not just when wide open, and speed adjustment by as much as 50% over variable orifice models. The wye
pattern, globe valve design and 5-turn, non-rising handle provides 20 times the adjustment precision of a
1
/
4
turn ball valve. For
1
/
2
to 2 inch (13 to 51 mm) pipe sizes, these valves are available for sweat, NPT or
BSPP pipe connections for installation convenience. All models include an adjustable memory stop, so
the valve can be easily returned to any required set point after system service.

ARMflo Series Split Case Valves
These 2
1
/
2
to 12 inch (64 to 305 mm) commercial/industrial grade circuit balancing valves provide the robust
construction, installation flexibility and long life required for large commercial building projects. The split case
design enables conversion from straight to elbow configuration in seconds, without additional parts or special
tools. System connections include industry standard grooves for lowest possible installed cost and ARMgrip
flange adapters or fixed flanges for installation convenience. The unique service seal enables stem packing
gland replacement under pressure, eliminating the need for unscheduled system shut-down and draining.

Flow Measurement Equipment
CBDM analog and DPM digital manometers provide reliable differential pressure readings for HVAC system
balancing and trouble-shooting using comprehensive performance charts and balancing tools available
from Armstrong. The 2
1

2
to 12 inch (64 to 305 mm) APO orifice plates or APV venturis may be close
coupled to split-case CBVs or remote mounted for fixed orifice flow calibration speed and measurement
accuracy to ±1%.
Armstrong KNX Series Hydronic Hook-Up Kits integrate the components required to connect piping to hydronic heating or
chiller system equipment. These kits are available in connection sizes from
1
/
2
to 2 inch (13 to 51 mm) and are configured to the
system designer's specifications. Each kit is tested, bagged, tagged, boxed and labeled at the factory prior to shipment to the
building site.
Pre-engineered, pre-assembled, pre-tested KNX Hydronic Hook-up Kits:
f
Virtually eliminate engineering/compatibility verification effort and issues
f
Reduce the component count per HVAC device by up to 80%
f
Reduce on-site component connections from as many as 54 to as few as 4
f
Ensure the correct components are installed at the correct location in the system
f
Reduce the risk of leaks and re-work after the pressure test
