1 Safety instructions and measures
Intended use
TheType2489Pressure-independentControlValve(PICV)withconnectionforadditional
electricactuatorandcontrolthermostatisintendedfortheowandtemperaturecontrolof
liquidsupto150°C.ThecombinedType2489/5824or5827/2430ismainlyusedin
district heating supply networks. The regulators and actuators are designed to operate under
exactlydenedconditions(e.g.operatingpressure,processmedium,temperature).
Therefore, operators must ensure that the regulators and actuators are only used in operating
conditionsthatmeetthespecicationsusedforsizingthedevicesattheorderingstage.In
case operators intend to use the devices in applications or conditions other than those
specied,contactSAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the
device for its intended purpose or for damage caused by external forces or any other
external factors.
ÎRefertothetechnicaldataandnameplateforlimitsandeldsofapplicationaswellas
possible uses.
Reasonably foreseeable misuse
The regulator is not suitable for the following applications:
− Useoutsidethelimitsdenedduringsizingandbythetechnicaldata
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described
− ModicationofpartsaswellasserviceorrepairworkonTÜV-testedType2489/5825-
x,Type2489/5827-AandType2489/TROVIS5725-x
Qualications of operating personnel
The regulator must be mounted, started up, serviced and repaired by fully trained and
qualiedpersonnelonly;theacceptedindustrycodesandpracticesmustbeobserved.
According to these mounting and operating instructions, trained personnel refers to
individualswhoareabletojudgetheworktheyareassignedtoandrecognizepossible
hazardsduetotheirspecializedtraining,theirknowledgeandexperienceaswellastheir
knowledge of the applicable standards.

Safety instructions and measures
Personal protective equipment
Werecommendcheckingthehazardsposedbytheprocessmediumbeingused(e.g.
uGESTIS(CLP)hazardoussubstancesdatabase).
ÎProvide protective equipment (e.g. safety gloves, eye protection) appropriate for the pro-
cess medium used.
ÎWear hearing protection when working near the valve. Follow the instructions given by
the plant operator.
ÎCheckwiththeplantoperatorfordetailsonfurtherprotectiveequipment.
Revisions and other modications
Revisions,conversionsorothermodicationsoftheproductarenotauthorizedbySAM-
SON.Theyareperformedattheuser'sownriskandmayleadtosafetyhazards,forexam-
ple. Furthermore, the product may no longer meet the requirements for its intended use.
Safety features
TheType2489Pressure-independentControlValve(PICV)withanelectricactuatorwithout
fail-safe action does not have any special safety features.
TheType2489Pressure-independentControlValve(PICV)withanelectricactuatorwithfail-
safe action moves to a certain fail-safe position upon supply voltage failure. The fail-safe
actionofSAMSONactuatorsisspeciedontheactuatornameplate.
When relieved of pressure, the valve with an open restriction without electric actuator and
Type2430Thermostatisopenedbytheforceofthesetpointsprings.
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
preventhazardsthatcouldbecausedinthedevicebytheprocessmedium,theoperating
pressure or by moving parts by taking appropriate precautions. Plant operators and operat-
ingpersonnelmustobserveallhazardstatements,warningsandcautionnotesinthese
mounting and operating instructions, especially for installation, start-up and service work.
Wealsorecommendcheckingthehazardsposedbytheprocessmediumbeingused(e.g.
uGESTIS(CLP)hazardoussubstancesdatabase).
ÎObservesafetymeasuresforhandlingthedeviceaswellasrepreventionandexplosion
protection measures.

Safety instructions and measures
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions as well as the refer-
enced documents to the operating personnel and to instruct them in proper operation. Fur-
thermore, operators must ensure that operating personnel or third parties are not exposed to
any danger.
Operatorsareadditionallyresponsibleforensuringthatthelimitsfortheproductdenedin
the technical data are observed. This also applies to the start-up and shutdown procedures.
Start-up and shutdown procedures fall within the scope of the operator's duties and, as such,
are not part of these mounting and operating instructions. SAMSON is unable to make any
statements about these procedures since the operative details (e.g. differential pressures and
temperatures) vary in each individual case and are only known to the operator.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
wellasthereferenceddocumentsandobservethespeciedhazardstatements,warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced standards, directives and regulations
The regulators comply with the requirements of the European Pressure Equipment Directive
2014/68/EUandtheMachineryDirective2006/42/EC.RegulatorswithaCEmarking
have a declaration of conformity which includes information about the applied conformity
assessment procedure. The EU declaration of conformity is included in the annex of these
instructions(seesection9.2).
Non-electric valve versions whose bodies are not lined with an insulating material coating do
nothavetheirownpotentialignitionsourceaccordingtothehazardassessmentstipulatedin
Clause5.2ofISO80079-36,evenintherareincidentofanoperatingfault.Therefore,such
valveversionsdonotfallwithinthescopeofDirective2014/34/EU.
ÎForconnectiontotheequipotentialbondingsystem,observetherequirementsspeciedin
Clause6.4ofEN60079-14(VDE0165-1).

thermostatconsistsoftheType2489Flow
Regulator,theTROVIS57xx/Type58xx
ElectricActuatorandtheType2430Control
Thermostat.Thevalveisttedwitha
connecting piece (8) for connection of an
electric actuator and the control thermostat.
As a result, it is possible to transmit the
control signal of an electric control device
(owrate)andacontrolthermostat
(temperature). The entire regulator assembly
isusedtomaintaintheowrateand
temperature constant at their adjusted set
points.
The valve closes as the controlled variables
(owrateand/ortemperature)rise.
Types5824-10, 5827-x1 and 5825-10
Electric Actuators with a 7.5mm rated travel
are used for valves in sizes DN15 to 25.
Types5824-20, 5827-x2 and 5825-20
Electric Actuators with 12mm rated travel
are required for valves in valve sizes DN32
to 50.
NOTICE
!
For higher temperatures and the resulting
thicker insulation of the valve, mount an
intermediate insulating piece (order no.
1992-3132) between the connecting piece
and actuator.
Themediumowsthroughthevalveinthe
direction indicated by the arrow on the valve
body.Theowrateisdeterminedbythear-
ea released by the valve plug (3) and the
adjustable restriction (8.5 or 8.6).
The installed set point spring (5) determines
the differential pressure across the restriction
of0.2bar.Thepressureupstreamofthere-
striction (8.5 or 8.6) is transmitted over the
control line (11) to the upstream pressure
side of the actuator. The pressure down-
stream of the restriction acts on the low-pres-
sure side of the operating diaphragm (6.1)
through a hole in the valve plug. The differ-
ential pressure generated across the restric-
tion is converted into a positioning force by
the operating diaphragm. This force is used
to move the valve plug depending on the
forceofthesetpointspring(5).Theowrate
is adjusted at the set point screw (8.3) or set
point adjuster (8.2).
