FlowCal™and FlowCal+™ Y-body Automatic Balancing Valve
128 series
The FlowCal™ and FlowCal+™ 128 Series Y-body automatic flow balancing valve
is pressure independent and maintains a fixed flow rate as differential pressures
vary. It incorporates an exclusive flow cartridge made of an anti-scale, low noise
polymer. Constructed of DZR low-lead brass, FlowCal and FlowCal+ 128 Series
are ideally suited for flow rate balancing in plumbing applications such as hot
water recirculation systems and can also be used in hydronic applications. The
FlowCal+ 128 Series provides a built-in check valve to protect against circuit
thermo-siphoning. The outlet temperature gauge (optional) verifies the fluid
temperature in the circuit.

SAFETY INSTRUCTION
WARNING: This product can expose you to chemicals including lead, which
is known to the State of California to cause cancer and birth defects or other
reproductive harm. For more information go to www.P65Warning.ca.gov.
CAUTION: All work must be performed by qualified personnel trained in the
proper application, installation, and maintenance of systems in accordance
with all applicable codes ordinances.
CAUTION: Over-tightening and breakage can occur with the use of Teflon®
pipe joint compounds. Teflon® provides lubricity so that care must be
exercised not to over-tighten joints. Failure to follow these instructions could
result in property damage and / or personal injury.
CAUTION: System fluids under pressure or temperature can be hazardous.
Be sure the pressure has been reduced to zero and the system temperature
is below 100℉ (38℃). Failure to follow these instructions could result in
property damage and/or personal injury.
CAUTION: Clean the pipes of any debris, rust, incrustations, welding slag
and any other contaminants. For optimal operation, air in the system must
be removed.
CAUTION: If the FlowCal is not installed, commissioned and maintained
properly, according to the instructions contained in this manual, it may not
operate correctly and may endanger the user.
CAUTION: Make sure that all the connecting pipework is water tight.
Caleffi shall not be liable for damages resulting from stress corrosion, misapplication or misuse
of its products..
This safety alert symbol will be used in this manual to draw attention to safety related
instructions. When used, the safety alert symbol means ATTENTION! BECOME ALERT!
YOUR SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE INSTRUCTIONS
MAY RESULT IN A SAFETY HAZARD.

CONSIGNE DE SÉCURITÉ
AVERTISSEMENT: Ce produit peut vous exposer à des produits chimiques
comme le plomb, qui est connu dans l’État de Californie pour causer le
cancer, dommages à la naissance ou autre. Pour plus d’informations rendez-
vous www.P65Warnings.ca.gov.
AVERTISSEMENT: Tous les travaux doivent être effectués par du personnel
qualifié formé à la bonne application, installation et maintenance des
systèmes conformément aux codes et règlements locaux.
AVERTISSEMENT: Un serrage excessif et une rupture peuvent survenir
avec l’utilisation de Teflon® composés de joint de tuyau. Le Teflon® offre
un pouvoir lubrifiant de sorte que les soins doivent être exercé pour ne pas
trop serrer les joints. Non-respect de ces instructions pourrait entraîner des
dommages matériels et / ou des blessures corporelles.
AVERTISSEMENT: Les liquides du système sont sous pression ou de la
température peivent être dangereux. Être sûr que la pression a été réduite
à zéro et la température du système est inférieure à 100℉ (38℃). Le non-
respect de ces instructions peut entrainer des dommages matériels et/ou des
blessures.
AVERTISSEMENT: Nettoyer les tuyaux de tout debris, roille, incrustations,
scories de soudure et d’autres contaminants.Pour un fonctionnement optimal,
de l’air dans le system doit etre retire.
AVERTISSEMENT: Si le FlowCal en Y, n’est pas installe, mis en service et
Entretenu correctement, selon les instructions contenues dans ce manuel, il
Peut ne pas fonctionner correctement et peut mettre en danger l’utilisateur.
AVERTISSEMENT: S’assurer que tous les raccordements sont étanches.
Caleffi ne pourra etre tenue responsable des dommages resultant de la corrosion, d’une
mauvaise utilisation ou une mauvaise utilisation des produits.
Ce symbole d’avertissement servira dans ce manuel à attirer l’attention sur la sécurité
concernant instructions. Lorsqu’il est utilisé, ce symbole signifie. ATTENTION! DEVENEZ
ALERTE ! VOTRE SÉCURITÉ EST EN JEU ! NE PAS SUIVRE CES INSTRUCTIONS PEUT
PROVOQUER UN RISQUE DE SECURITE.

Installation:
Install the FlowCal automatic balancing valves on the circuit return pipe (either the domestic
hot water recirculation return branch before the main return trunk or after the coil of an HVAC
system). Make sure the flow direction arrows on the 128 body match the system’s flow direction.
It is important to allow easy access to the FlowCal for future inspection and maintenance.
Isolation valves
Isolation ball valves on both the inlet and outlet of the FlowCal balancing valve are highly
recommended for easy servicing. The Caleffi 290030 isolation valve is convenient and compact;
it fits between the FlowCal body and the union tailpieces.
Flow verification
Factory-installed PT ports allow for differential pressure verification by balancing contractors. As
long as the measured DP is within the range for the given cartridge, per the label, the flow rate
will be equal to the GPM shown on the label.
Polymer flow cartridge
The flow rate cartridge is made of an anti-scale polymer specially engineered for use in cooling,
heating and domestic water systems, to prevent mineral buildup in a wide range of working
temperatures. It features high resistance to the abrasion caused by continuous fluid flow, is
insensitive to the deposit of scale and is fully compatible with glycols and additives used in
circuits.
FlowCal 128…AF and FlowCal+ 128…AFC series
FlowCal+ models come with a check valve in the inlet tailpiece to prevent reverse flow in
domestic hot water recirculation applications. In addition, models are available with and without
an outlet temperature gauge to verify water temperature when balancing the system. The
standard FlowCal models do not include a check valve and are not available with the outlet
temperature gauge. Either series can be used in domestic hot water or hydronic heating/cooling
applications.

Serviceability
The Y-body style of the 128 Series FlowCal and
FlowCal+ balancing valves allow the body to remain
in the piping when accessing the cartridge which
simplifies serviceability and cleaning.
Pre-commissioning system flush
The cartridge can be easily removed for system
flushing prior to commissioning. Remove the access
plug and the flow cartridge, attach the cartridge to the
body using a zip tie, and reinstall the cartridge after
the system has been thoroughly cleaned.
Replaceable cartridge
The internal regulator is assembled in the form of a self-contained cartridge to permit easy
removal from the body for inspection or replacement. It is equipped with a special wire
mechanism for fast and safe positioning without tools. If the cartridge gets replaced with a new
cartridge that has a different flow rate, be sure to apply the new matching body label.
