1. Introduction
• Albion Valves (UK) Ltd ART 20C is a Pressure Independent Control Valve (PICV) which can
 beusedtoregulatethepressuredifferentialinacircuitandtocontroltheamountofuid
 owingthroughit.
•  Thankstotheiruniquedesign,PICV’scanperformowregulation,differentialpressure
control and modulation for comfort control.
Flow Regulation
When an electric actuator is not present or the plastic cap has been removed, the valve is
normally open. But if the plastic cap is screwed on, or an electric actuator is installed, the spring
forces the valve to close. The inlet water passes through a modulating control component whose
geometrycanbemodiedbyturningthepre-settingdialtoobtaintherequiredowrateforthe
branch of the system where the valve is installed.
Differential Pressure Control
PICVmaintainssteadyowrateevenwhentherearepressureuctuations.TheDPCbonnet
hastwodifferentpressures.Therstoneisinthepassageconnectingthevalveinlettothe
upper section of the valve (see hydraulic diagram); the second one is at the valve outlet near
the“pa”owrateselectingdevice.Inordertomaintainthesepressuredifferences,theDPC
bonnetobturatorrestrictstheboreofthewateroutlettoachievethepre-setowrate,evenifthe
pressuresinthesystemuctuate.
Modulation
Fullauthority”owratemodulationforroomtemperaturecontrol;Theactuatorperformsthe
modulatingfunctionchangingthesectionofowpassage.
When continuous modulation is carried out, the temperature is kept under control. ART 20C
keeps the same obturator stroke, regardless of the presetting dial position. With continuous
modulation,controlisexcellentevenwithsmallowopeningsandthiseliminatestheon/off
effect.
Constantowisobtainedthroughthevalve,despitepressureuctuations.
Bysimplymeasuringdifferentialpressureacrossthevalve,theowthroughthecartridgeis
obtained as follows:

3
ART 20C Rev 1
IfmeasureddifferentialpressureisaboveΔpmin(start-uppressure),theowrateisthesameas
theonestatedonthevalvetable(function)ofthepre-set;
IfmeasureddifferentialpressureisbelowminimumΔpminstatedonvalvetable,owrateis
calculated using the following formula:
Where:
Qistheowrateinm3/h,ristherelativedensity,Δpisthepressuredropacrossthevalve;
Kvs-Kvacrossthevalvewhenitisfullyopen

Albion Valves (UK) Ltd recommend that any ART 20C PICV are sized prior to installation to ensure
the correct valve selection.
3. Valve Features
• The ART 20C PICV can be used in conjunction with multiple actuators to open, close and
modulate the valve.
• Motorised Actuators
o C21V 24V AC 3 position control
o C22V 230V 3 position control
 o C23E24VAC0-10VDCcontrol

4. Valve Installation
• The valve should be sited to ensure ease of access.
• It is the responsibility of the installer to ensure the valve is suitable for service conditions
e.g., temperature, pressure, and service media.
• Itistheresponsibilityoftheinstallertoensurethattherequiredowrateiswithinthe 
valves operating range.
• Wheretted,removeangeprotectors/dustcapsandallotherpackagingmaterial.
• Careshouldbetakentoensurethesurfacenishofthevalveisprotectedduring 
installation.
• The valves may be installed in horizontal or vertical pipework, but the actuator must never
be sited underneath the valve.
• Thevalveisuni-directionalandshouldonlybeusedforowinthedirectionshownonthe
valve.
• Suitablegaskets/sealingmaterialshouldbeusedduringinstallation.
• When setting the valve, the valve can be set by rotating the adjustment knob which sits
underneath the cap.

5. Balancing
• Removetheplasticcapfromthetopofthevalve.Turnthepre-setdial(seepicture)so 
 thatthemarkontherotatingpartmatchesthevalueindicatedonthexedpartofthe 
 device(1,2,3,etc.)whichcorrespondstotherequiredowrate.Donotexceedthe 
 setoperatingrange(1-5).
• Therelationbetweenthesettingdial,andowratescanbefoundinthetablesbelow.
• Using a differential manometer, check that the differential pressure is higher or the same
as the minimum value reported in the tables. The differential manometer interfaces with the
balancing valve through the two binder points of the valve. When balancing is achieved,
 lockthepre-settingdialbyscrewingitdowncompletely,preventingitfrom  
being unintentionally rotated.
