3. Valve Features
• Albion Valves (UK) Ltd ART 679 is designed to reduce a higher inlet pressure, to a lower,
constant, safer outlet pressure.
• Lead free pressure reducing valve housing.
• Enhancedcorrosionresistanceforallwaterqualities.

• Filter screen with 160µm mesh - protection of the system debris with easy access for
cleaning.
4. Valve Installation
• Albion Valves (UK) Ltd recommend that the installer adheres to the installation
 requirementsasspeciedbytheWaterSupplyWaterFittingsRegulations1999.
• ConsiderationshouldalsobegiventoBSEN806-2(Specicationsforinstallationsinside
buildings conveying water for human consumption).
• ART 679 should be sited to ensure ease of access, for both use and maintenance.
• It is the responsibility of the installer to ensure the valve is suitable for service conditions
e.g., temperature, pressure, and service media.
• Consideration shold always be given to galvanic corrosion during installation.
• It is the responsibility of the installer to ensure that the valve, and adjoining pipework is
suitably supported to avoid any undue stresses being applied to the valve.
• Suitable sealing materials should be used during installation.
• Do not clean any parts of the valve with harsh chemicals that may cause damage.
• ART 679 is factory-set to 3 bar outlet pressure (for SP version).
• ART 679 must be installed in the pipeline without stress. Make sure that the correct seals
 aretted,andonlysuitabletoolsareused.
• Itisadvisabletohaveanuninterruptedlengthof5xnominalpipediameterbothbefore
 andafterthevalvetoensurelaminarowatboththeinletandoutletofthevalve.This 
 shouldbeincreasedto10xupstreamwheninstalledimmediatelyfollowingasystem 
pump.
• Thepipelinemustbecarefullyushedthroughbeforethepressurereducerisinstalled.
This ensures that any impurities being carried along by the medium will not be trapped in
the valve as these may have a detrimental affect on the valve.
• The pressure gauge, positioned on the outlet side of the valve, enables the outlet pressure
to be validated and is screwed to the threads and sealed by means of a suitable sealing
tape.
• ART 679 can be installed in any given orientation.
• Aowvelocityofbetween1m/sand2m/sshouldbeadheredtoatalltimestoavoidthe
risk of cavitation and wear on the seat.
• Thedirectionofowmustmatchthearrowonthehousing.
• Albion Valves (UK) Ltd recommend that ‘shut-off’ valves are installed immediately before
and after pressure reducing valves.
Attention!
Before the pressure reducer is commissioned, it must be ensured that the two
pressure gauge connections on the housing are sealed by means of pressure
gauges or sealing plugs.

ART 679 Rev 1
5. Valve Setting
The required pressure is set by turning the adjustment knob, there are 2 ways to achieve the
required set pressure:
1) Setting using the adjusting scale
The setting can be made without operating pressure!
The adjusting scale, visible on both sides, indicates the required setting pressure.
Loosenthexingscrew,by1/4screwturn,ontheadjustmentknob(donotremove!)byturning
to the left. Turning the adjustment knob clockwise increases the back pressure and turning
anticlockwise reduces the back pressure. If necessary, check the pressure using a pressure
gauge.Nowre-tightenthexingscrew.
2) Setting using a pressure gauge
The setting can be made only with operating pressure!
Shut off the water supply and relieve the valve on the outlet side, e.g., by drawing off water,
andmakesurenofurtherdrawoffismade.Loosenthexingscrew,by1/4screwturn,onthe
adjustment knob (do not remove!) by turning to the left. If a setting below 3 bar (and/or the pre-
setting) is required, turn the adjustment knob to the left until the spring is completely relieved.
Restore the water supply and turn the adjustment knob to the right until the desired setpoint is
reached. If a setting above 3 bar (and/or the pre-setting) is required, restore the water supply
immediately and turn the adjustment knob to the right until the desired setpoint is reached.
When making the setting, bear in mind that the outlet pressure set for zero consumption will drop
further as water is drawn off due to pressure and friction losses. The degree of drop will depend
on the amount drawn off.
6. Maintenance
AccordingtoBSEN806-5,inspectionandmaintenancemustbecarriedoutat
least once per year to rectify any malfunctions that can be caused by contamination, corrosion,
calcication,andnaturalwear.Thisintervalmaybeshorter,dependingontheconditionsofuse.
During this maintenance / inspection procedure, the screen must be cleaned, the
valve insert checked for fault-free condition and must be replaced if required. Then check the
outletpressureiscorrectatzeroowandpeakow.Thefunctionofthevalvemustbechecked
following prolonged shutdowns.
Please ensure that the system is not under pressure during maintenance of the pressure
reducing valve.

Removing The Valve Insert
• Turn off the water supply and relieve pressure.
• Loosenthexingscrew,by1/4screwturn,ontheadjustmentknob(donotremove!)by
turning anti-clockwise.
• Turn the adjustment knob anticlockwise until the spring is completely relieved. Failure to
observe this instruction can cause injury.
• Loosen the hood using a spanner and remove the assembly.
• Remove the spring set, slip ring and valve insert.
• Clean / replace the valve insert as required.
• For assembly, proceed in the reverse sequence. Please note, a light lubrication may be
required during this process. Please ensure this is WRAS approved should the installation
require this.
• Set the desired setpoint as described previously.
Remove The Screen
• Shut off the water supply and relieve the valve of pressure.
• Loosenthelterscreencupbyhand/withaspannerbyturningCCWandremove.Ensure
 thatthelterscreencupisnotdamaged.Ifitisdamaged,replaceitwithanewpart.
• Remove the screen.
• Clean / replace the screen and grooved ring as required.
• Reassemble in the reverse sequence.
• Make sure that the grooved ring and the O-ring are in the correct position.
• Tightenthelterscreencupushbyhand(max.5Nm).
7. ApprovalsClassication
• PleasecontactAlbionValves(UK)LtdQualityDepartmentforfurtherdetailsofanyspecic
product approvals and accreditations.
8. Troubleshooting
ART 679, may from time to time malfunction. The most common causes, and how to rectify are
given below: -
Outlet pressure increases above setpoint
In this instance the valve insert / valve seat is likely to be contaminated or damaged. To rectify
either clean or replace.
Leakage from the spring hood
If water escapes from the spring hood it is likely that the spring hood is not correctly mounted or
the diaphragm is damaged.

ART 679 Rev 1
Low water pressure
If a low water pressure is prevalent on the outlet side, it is likely that the screen is clogged. This
canberectiedbycleaningorchangingthescreen.
A full risk assessment should be undertaken prior to any maintenance works taking place.
