ART 22
Technical Data
The Albion ART 22 is a fixed orifice double regulating valve used to regulate and
measure the flow passing through it.
Flow Coefficient
The flow rate can be calculated using the Kv value and a measured signal.
Kv = Q*36 Kvs = Q*36
√ ∆P √ ∆Ps
where Kv &Kvs = flow coefficient (m3/hr at 1 bar differential)
Q = flow rate (l/s)
∆P = headloss attributable to valve (kPa)
∆Ps = differential pressure across tappings (signal) (kPa)
Kvs Values

Kvs 0.62 1.1 2.3 5.3 9.2 19.0 22.1 42.3
Pressure Loss
The pressure loss across the fixed orifice double regulating valve is the combined
loss attributable to the orifice plated and double regulating valve in the fully open
position.

Kv 0.533 0.738 2.00 3.88 7.28 13.39 18.69 30.10
Installation
Fixed orifice double regulating valves must always be installed with a minimum of
5 pipe diameters of straight pipe, without intrusion, upstream of the orifice plate.
Downstream of the valve a minimum of 2 pipe diameters of straight pipe are
required.
Sizing
Once the required flow rate has been calculated, the size of the fixed orifice
double regulating valve can be determined based on the following:
The minimum signal at the design flow rate of 1 kPa.
For minimum pressure loss, a maximum signal of 4.7 kPa, which corresponds
to the maximum differential pressure range of a fluorocarbon manometer.

ART 22
This fixed orifice double regulating valve is a precision manufactured product and should be
handled, installed and used with care as detailed in these instructions.
ART 22 balancing valves are suitable for both heating (LPHW) and cooling
applications at working pressures up to 25 bar.
Operating Pressure and Temperature
DZR Fixed Orifice Double Regulating Valve
Limits of Use
The valve is rated PN 25 and must be installed in a piping system where the normal
pressure and temperature does not exceed the above ratings.
The upper temperature is restricted to 120°C due to the elastomeric seals in the test points.
Layout and Siting
It should be considered at the design stage where valves will be located to
give access for operation, regulation and setting to the required position.

ART 22
Installation
Valves are precision manufactured products and should not be subjected to misuse.
Careless handling, allowing foreign particles to enter the valve through the end ports, lack
of cleaning both valve and system before operation should be avoided. Excessive force
during pipe tightening and handwheel operation should be avoided.
Valves must be provided with adequate support. Adjoining pipework must be supported
to avoid the imposition of pipeline strain onto the valve, which would impair its
performance.
Immediately prior to installation, the adjacent pipework should be checked for
cleanliness and freedom from debris.
Confirm that the pipe threading is correct to avoid excessive penetration of the
pipe into the valve, which may cause damage.
Thread sealing compounds appropriate to the application must be used but excessive
use should be avoided, since this increases thread interference and may cause
overstressing of the body ends and may cause thread seal to extrude into the bore,
disturbing the flow condition.
Ensure the threads are properly engaged before proceeding to tighten the valve
onto the pipe.
The wrench must only be located on the valve end into which the pipe is being
threaded to avoid distortion of the valve.
Fixed orifice double regulating valves should be installed with a minimum of 5 diameters
equivalent of straight pipe upstream and 2 diameters downstream having the same
nominal diameter as the valve and should not include any reducers or any
other intrusions into the bore within these specified lengths.
It is important to ensure that the flow arrow on the valve is coincident with the
direction of flow in the pipeline.

ART 22
Operating
When used for balancing water distribution systems, valves will always be in the fully open
position at commencement of any commissioning or flushing exercise.
Regulation is accomplished by rotating the handwheel clockwise when viewed
from the top of the handwheel.
The valve is opened by anti-clockwise rotation of the handwheel to a positive stop.
Further effort is not necessary. When fully open it is advantageous to rotate the
handwheel clockwise 1/2 turn.
To close the valve, the handwheel is rotated clockwise to a positive stop.
Test points
Valves are supplied with test points fitted.
Operation
The commissioning stage is the only time that the valve will normally have any attention.
During this stage, all entrained air must be removed from the system before
accurate measurements of differential pressure signals can be taken from the test
points.
There are two test points, each fitted with a coloured strap and captive cap.
• Upstream (HP) – Red • Downstream (LP) - Blue
For safety reasons, all manometer probe insertions must be carried out with the
system cold.
The measurements are taken by directly inserting the test probe into the test point.
A silicone oil or grease should be lightly applied to the shaft of the probe prior to
insertion. No other type of lubricant should be used.
Valve Setting
When the regulated position is achieved, the double regulating feature is set as
follows:
• The inner spindle is adjusted through the central hole in the handwheel, using
a 3mm Allen key.
• Rotate the inner spindle anti-clockwise until a stop is felt.
• The double regulating feature is now set which enables the valve to be fullyclosed
for isolation and re-opened to the previously set position. It is recommended to record
this set position for reference later if necessary.
Maintenance
The Albion Art 22 does not require any routine maintenance.
