FLOWMATIC® Pressure Independent Control Valve (PICV)

The pressure independent control valve is a device composed of an automatic

ﬂow rate regulator and a control valve with optional actuator. The device can

adjust ﬂow rate and keep it constant in the presence of changing differential

pressure conditions of the circuit in which it is installed.

Flow rate is adjusted in two different ways:

-manually on the automatic ﬂow rate regulator, to restrict the maximum value.

-automatically by the control valve in combination with a proportional (0–10 V) or

ON/OFF actuator, in accordance with the thermal load requirements of the circuit

to be controlled.

The pressure independent control valve (PICV) is supplied complete with pressure

test ports for conﬁrming pressure differential and ﬂow rate.

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 145 valve 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 145 vanne 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:

℉Assembly and disassembly of the valve should always be carried out while the system

is cold and not under pressure.

℉The valve without actuator can be installed in any position. When using an actuator the

valve can be installed in any position except upside down.

℉Indoor use only. When installed with actuator consult actuator instruction sheet for

details on ambient temperature, humidity and ﬂuid temperature restrictions.

℉If installed with an actuator and inside an enclosure it is important to ensure that there

is adequate ventilation inside the enclosure itself.

℉When valve is installed, the direction of ﬂow must be observed.

℉Valve must be installed in a manner to allow easy access for inspection and

maintenance.

Maximum ﬂow rate adjustment

Unscrew the protective cap by hand to gain access to the maximum ﬂow

rate locking nut (10), which can be turned with a 19 mm wrench. Attached

to the locking nut is a 10-position graduated scale. Refer to the “Flow rate

adjustment table” below to determine the correct numerical position based

on the design ﬂow rate of the circuit being served. Turn the locking nut, lining

up the desired numerical position with the notch on the valve (12).

Adjustment procedure:

Flow rate confirmation

During operation the differential pressure across the valve is observed using a manometer

connected to upstream (A) and downstream (B) test ports on the valve. If the differential pressure

is greater than the minimum ∆P of the valve at the selected flow rate and less than the maximum

∆P, the valve is supplying the flow rate for which it has been set up. Refer to the “Flow rate

adjustment table” to determine minimum ∆P. Maximum ∆P is 58 psi.

Shut-off

With the protective cap installed, manual shut-off is possible with the integrated knob. Turn

clockwise to shut-off flow, turn counterclockwise to open.

Optional Actuators:

Actuator installation:

• Protective cap on valve must be removed before actuator installation.

• Do not supply power to the actuator until it is installed on the valve.

• For 6565 Series actuators, thread clip onto valve fully and fit actuator to clip (N).

• For 145 Series actuators, thread onto valve fully (M).

• Connect the actuator to external controls (BMS or similar) to operate actuator.

• Consult actuator instruction sheet for details on wiring and setup

Maintenance:

After final commissioning, release the air that has built up at the top of the valve body by using

a screwdriver to loosen screw at bottom of valve, without fully removing. Re-tighten screw at

the end of the procedure (O).
