1 Safety instructions and safety measures
Intended use
TheSAMSONType41-23RegulatorconsistsofaType2412ValveandaType2413Actua-
tor. The valve and actuator (except for tested regulators) are delivered separately and must
be assembled together according to these instructions.
The self-operated regulator is used to control the downstream pressure p2in the pipeline to
the adjusted set point. Liquids, gases and vapors in processing and industrial plants can be
controlled by the regulator.
Theregulatorsaredesignedtooperateunderexactlydenedconditions(e.g.operating
pressure, process medium, temperature). Therefore, operators must ensure that the regulators
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 regulators in other applications or
conditionsthanspecied,contactSAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice 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 regulators are not suitable for the following applications:
−Useoutsidethelimitsdenedduringsizingandbythetechnicaldata
−Useoutsidethelimitsdenedbytheaccessoriesmountedontheregulator
Furthermore, the following activities do not comply with the intended use:
−Use of non-original spare parts
−Performing service and repair work not described in these instructions
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aretobeobserved.Accord-
ing 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appli-
cable standards.

Safety instructions and safety measures
Personal protective equipment
Werecommendcheckingthehazardsposedbytheprocessmediumbeingused(e.g.
uGESTIS(CLP)hazardoussubstancedatabase).
ÎProvide protective equipment (e.g. safety gloves, eye protection) appropriate for the pro-
cess medium used.
ÎWear hearing protection when working near the regulator.
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SAMSON.
Theyareperformedattheuser'sownriskandmayleadtosafetyhazards,forexample.Fur-
thermore, the product may no longer meet the requirements for its intended use.
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regulatorbytheprocessmedium,theoperating
pressureorbymovingpartsbytakingappropriateprecautions.Theymustobserveallhaz-
ard statements, warning and caution notes in these mounting and operating instructions, es-
pecially 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substancedatabase).
ÎObservesafetymeasuresforhandlingthedeviceaswellasrepreventionandexplosion
protection measures.
Safety features
TheType41-23Regulatordoesnothaveanyspecialsafetyfeatures.Whenrelievedofpres-
sure, the regulator is opened by the force of the set point springs.
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions as well as the
referenced documents to the operating personnel and to instruct them in proper operation.
Furthermore, the operator must ensure that operating personnel or third persons are not ex-
posed to any danger.

EB 2512 EN 7
Safety instructions and safety measures
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, the operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced standards and regulations
TheregulatorscomplywiththerequirementsoftheEuropeanPressureEquipmentDirective
2014/68/EU.RegulatorswithaCEmarkinghaveanEUdeclarationofconformity,which
includesinformationabouttheappliedconformityassessmentprocedure.ThisEUdeclaration
ofconformityisincludedintheAppendixoftheseinstructions(seesection10.3).
AccordingtotheignitionriskassessmentperformedinaccordancewithEN13463-1:2009,
section 5.2, the non-electrical regulators do not have their own potential ignition source even
in the rare incident of an operating fault. As a result, they do not fall within the scope of Di-
rective 2014/34/EU.
ÎForconnectiontotheequipotentialbondingsystem,observetherequirementsspeciedin
section6.4ofEN60079-14(VDE0165Part1).

Safety instructions and safety measures
1.2 Notes on possible personal injury
WARNING
!
Risk of personal injury due to residual process medium in the regulator.
While working on the regulator, residual process medium can escape and, depending
on its properties, may lead to personal injury, e.g. (chemical) burns.
ÎIf possible, drain the process medium from all the plant sections concerned and the
regulator.
ÎWear protective clothing, safety gloves and eyewear.
Risk of burn injuries due to hot or cold components and pipelines.
Depending on the process medium, regulator components and pipelines may get very
hot or cold and cause burn injuries.
ÎAllow components and pipelines to cool down or heat up.
ÎWear protective clothing and safety gloves.
Risk of personal injury due to loaded springs.
The set point springs of regulators with adjusted set point are preloaded and are under
tension.
ÎBefore starting any work on the springs, relieve the compression from the preload-
ed springs.

Design and principle of operation
3 Design and principle of oper-
ation
ÎRefertoFig.3
The Type 41-23 Pressure Reducing Valve
consistsofaType2412ClosingValveanda
Type2413Actuator.Thevalveandactuator
are delivered separately and must be assem-
bled according to the instructions in sec-
tion6.1.1.
The pressure reducing valve is used to main-
tain the pressure downstream of the valve to
an adjusted set point.
Theprocessmediumowsthroughthevalve
between seat (2) and plug (3) in the direc-
tion indicated by the arrow on the body. The
position of the valve plug determines the
owrateand,asaresult,thepressureratio
across the valve. The plug stem is sealed by
a frictionless bellows (5.1). The downstream
pressure p2is transmitted over the compen-
sation chamber (18) (for liquids above
150°Candforsteam)andthecontrolline
(17) to the operating diaphragm (12) (oper-
ating bellows (12.1) in the version with bel-
lows actuator) where it is converted into a
positioning force. This force is used to move
the valve plug depending on the force of the
set point springs (7). The spring force is ad-
justable at the set point adjuster (6). The
valves with KVS4andhigherhaveabalanc-
ing bellows (4). The upstream pressure acts
on the outside of the bellows and the down-
stream pressure on the inside of the bellows.
As a result, the forces produced by the up-
stream and downstream pressures acting on
the plug are balanced out.
Depending on the valve and actuator used,
the regulator can be upgraded to create a
pressurereducingvalveforlowowrates,a
steam pressure reducing valve or a pressure
reducing valve with increased safety (actua-
tor with two diaphragms).
The valve closes when the downstream pres-
sure rises.

Design and principle of operation
3.1 Technical data
The valve and actuator nameplates provide
information on the valve and actuator ver-
sions(seesection2.1).
Process medium and scope of application
TheType41-23PressureReducingValveis
used to maintain the pressure downstream of
the regulator to an adjusted set point.
−For liquids, gases or vapors
−Max. temperature 350°C
−Set points from 0.05 to 28bar
−ValvesizeDN15 to 100
−Pressure ratings from PN16 to 40
The regulator is open when relieved of pres-
sure. The valve closes when the downstream
pressure rises.
Temperature range
Dependingonhowtheregulatoriscong-
ured, it can be used up to temperatures of
350°C(Table1).Theminimumtemperature
is limited by the accessories used and the ac-
tuator's diaphragm material (uT2595).
Leakage class
The metal-seated regulator has the leakage
classIaccordingtoIEC60534-4.
The soft-seated regulator has the leakage
classIVaccordingtoIEC60534-4.
Noise emission
SAMSON is unable to make general state-
ments about noise emission as it depends on
the regulator version, plant facilities, process
medium and operating conditions.
Risk of hearing loss or deafness due to loud
noise.
Wear hearing protection when working near
the regulator.
The Type41-23 Pressure Reducing Valve is
not a safety valve. If necessary, a suitable
overpressure protection must be installed on
site in the plant section.
Dimensions and weights
Table5providesasummaryofthedimen-
sions and weights. The lengths and heights
in the dimension diagrams are shown on
