Armstrong Astro 2 hot water re-circulation systems
automatically circulate water through domestic hot water
distribution pipes. This helps to ensure that everyone in the
household has ‘instant’ hot water at the tap when they need
it, while also helping to conserve water and save water heating energy costs. All systems are assembled, wired, tested
and then shipped, ready for installation.

application
Armstrong 24 hour timers provide on/o pump control
according to preset operating times in order to increase
occupant comfort and improve the overall eciency
of domestic hot water re-circulation systems. The 24
hour timers are designed only for use with specified
Armstrong Astro series wet rotor circulators installed in
indoor hot water re-circulation applications.
Typical timer applications will cycle the pump at preset
times, allowing the user to select operation of the circulating pump during high peak usage periods in order to
decrease the delivery time to outlet fixtures and reduce
wasted water.
The timer control is programmable to ¼ hour intervals
within a 24 hour time frame utilizing a user-friendly
analog clock timer with hour and minute hands, two
directional arrows, and am/pm time setting.

installation
ARMflo Circuit Balancing Valves are highly
resistant to turbulence induced by nearby piping
components and can often provide excellent
results when mounted directly to other fittings.
However, for optimum flow measurement
accuracy and when practical, locate the valve:
• 5 pipe diameters downstream of a fitting.
• 2 pipe diameters upstream of a fitting.
• 10 pipe diameters upstream or
downstream of a pump.

* Armstrong low flow circuit balancing valves are needed for systems where the
flow rate is below ashrae guidelines. Low flow units allow contractors to line
size the valve, despite the low flow velocity. In addition, low flow valves:
• Boost the dierential pressure signal to make the signal more stable
and reliable
• Provide superior flow regulation over the operating range
• Are less prone to blockage due to particles in the system fluid
• Accurately indicate a blockage condition

notes
1
Solder style models - Valve body must be opened at
least one full turn prior to being soldered in the line.
2 For valve sizing, refer to the performance curve and
flow rate ranges. For balancing, use Venturi Cv curves
or slide rule, which display dierential pressure drop
across the Venturi for dierent flow rates.
3 Suggested dierential pressure meters for use with
Armstrong cbv’s are dpm-15 and dpm-100 digital
dierential pressure meters and cbdm 135/60 and cbdm 200 analogue meters.

installation
Generally locate the valve five pipe diameters
downstream from a fitting; with two diameters
downstream from the balancing valve free
from fittings. If a balancing valve is located
downstream from a circulation pump, allow
a distance of ten (10) diameters between the
pump and balancing valves (as illustrated
below). To save space, the valve may be used
in the angled configuration as an elbow.

installation
Generally locate the valve five pipe diameters
downstream from a fitting; with two diameters
downstream from the balancing valve free
from fittings. If a balancing valve is located
downstream from a circulation pump, allow
a distance of ten (10) diameters between the
pump and balancing valves (as illustrated
below). To save space, the valve may be used
in the angled configuration as an elbow.

Armstrong component grooves comply with the following
pipe standards for cut groove connections:
• ansi b36.10
• bs1387 (iso65)
• din2440 & 2448 (iso4200)
• jis g3452
Some pipe standards have more than one o.d. per nominal
pipe size. Always specify pipe o.d. to match component
grooves connections.
application
ARMgrip™ Flange Adapter Kits quickly convert industry standard
grooved pipe connections to flanged connections, as required to
suit application requirements. Armstrong grooved products (such
as cbv-g, afo-g, ftv-g and ssg) include special tabs that engage
the flange adapter to prevent rotation during installation, just like a
fixed flange. While grooved connection components may provide
the greatest initial and installed cost economy, optional ARMgrip™
flange adapters enable the widest range of on-site application
versatility, while reducing spare parts costs and inventory.

pt ports & extensions
Armstrong pt ports enable the quick connection of pressure
and temperature measuring instruments for testing, balancing,
and troubleshooting hydronic systems. The dual epdm seals
provide superior protection against leaks in either heated or
chilled water systems, and are compatible with water and
ethylene or propylene glycol anti-freeze solutions. The ¼" npt
male mounting thread mates with common pipe fittings and
the V" flared thread port mates with compatible instrument
probes such as those used with an Armstrong dpm dierential
pressure manometer. Two sizes of ¼" nptm × f extensions are
available to improve the accessibility of pt ports that are mounted
in hard-to-reach locations or where pipe insulation is used.

The Dierential Pressure Manometer (dpm) is a rugged,
digital instrument used to measure the pressure drop or
pressure gain across hydronic system components. The
dpm is available in either 0-15 psi or 0-100 psi measurement
range models for precise adjustment of circuit balancing
valves, and to monitor circulator performance. Both models
measure gauge or dierential pressure and can store up to
40 readings for later recall. The operator can select from
a variety of Imperial and metric measurement units to suit
the hydronic system design data. Valuable safety features
include visible and audible instrument over-range warning
alarms and backlit display for work in poorly illuminated
areas. The lightweight, compact dpm design is easy to
use in the tight, overhead spaces commonly encountered
when balancing or troubleshooting hydronic systems.

sizing information
When sizing an Armstrong Venturi, model apo, for a given pipe
size, locate the operating gpm on the performance curve. Select the
apo with a pressure drop (P) as near to, but always above10".
1 Measure the dierential pressure (p) across ports a & b
(fig. 1) of the ARMflo cbv.
2
Using the cbv Rule, turn the wheel of the slide rule
(fig. 2) until the measured pressure drop appears in
window. For example, for the slide rule shown in fig. 2,
the wheel is turned reveal 3.00 in the window.
3
Read the flow for the particular size of valve installed.
In this case, the reading
for a O" valve would be
5.96 USgpm.
4
The flow calculation for
other valve sizes appear
on either side of the
center rivet.
fig. 1
5
In the event that the calculated flow is not within the
desired range, turning the handle clockwise will decrease
the flow and turning the handle anticlockwise will increase
the flow.
Alternatively, or if a more precise flow rate calculation is
required, use the flow rate formula and corresponding Cv
value for the cbv model measured.

The venturi design also results in higher

Armstrong in-line circulators are favoured by
system designers and chiller/boiler manufacturers who prefer 3-piece construction for
reliability, eciency, and serviceability. Today’s
models are direct substitutes for all compatible circulators built over the last 50 years.
Armstrong Gold Series - Pump Less Volute kits
enable you to upgrade and renew circulators
manufactured by others, to gain the benefits of
Armstrong quality, service, and performance,
along with these design innovations.
