1 Safety instructions and measures
Intended use
TheType2488Pressure-independentControlValve(PICV)withanelectricactuatorisintend-
edforowcontrolofliquidsupto150°Candgasesupto80°C.Thepressure-independent
control valves are mainly used in district heating supply networks. The regulator and actuator
aredesignedtooperateunderexactlydenedconditions(e.g.operatingpressure,process
medium, temperature). Therefore, operators must ensure that the valve and actuator are only
usedinoperatingconditionsthatmeetthespecicationsusedforsizingthedevicesattheor-
dering stage. In case operators intend to use the devices 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 device 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 in these instructions
−Changingparts,serviceorrepairworkonTÜV-testedType2488/5x25-xand
Type2488/TROVIS5x25-x
Safety features
TheType2488Pressure-independentControlValve(PICV)withanelectricactuatorwithout
fail-safe action does not have any special safety features.
TheType2488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 ac-
tionofSAMSONactuatorsisspeciedontheactuatornameplate.
When relieved of pressure, the valve without actuator and with an open restriction is opened
by the force of the set point springs.

1.2 Notes on possible personal injury
WARNING
!
Damage to health relating to the REACH regulation.
If a SAMSON device contains a substance which is listed as being a substance of very
high concern on the candidate list of the REACH regulation, this circumstance is indi-
cated on the SAMSON delivery note.
ÎInformation on safe use of the part affected, see uwww.samson.de/reach-en.html.
Risk of personal injury due to residual process medium in the valve.
While working on the valve, 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 affected and the
valve.
ÎWear protective clothing, safety gloves and eye protection.
Risk of personal injury through incorrect operation, use or installation as a result of
information on the regulator being illegible.
Over time, markings, labels and nameplates on the regulator may become covered
withdirtorbecomeillegibleinsomeotherway.Asaresult,hazardsmaygounno-
ticed and the necessary instructions not followed. There is a risk of personal injury.
ÎKeep all relevant markings and inscriptions on the device in a constantly legible
state.
ÎImmediately renew damaged, missing or incorrect nameplates or labels.

1.3 Notes on possible property damage
NOTICE
!
Incorrect control due to the formation of ice on the regulator.
Mediumtemperaturesbelow0°Cmaycauseicetoformontheregulator,depending
on the air humidity. This may affect, in particular, the functioning of the plug or dia-
phragm stem guide.
ÎPrevent the formation of ice by taking appropriate precautions (e.g. enclosure,
trace heater etc.). The plant operator is responsible for selecting and implementing
appropriate precautions.
Risk of damage to the electric actuator due to the supply voltage exceeding the per-
missible tolerances.
The electric actuators are designed for use according to regulations for low-voltage in-
stallations.
ÎObserve the permissible tolerances of the supply voltage.
Risk of actuator damage due to excessively high tightening torques.
The connection of the electric actuator (with process controller) must be tightened with
certain torques. Excessively tightened torques lead to parts wearing out quicker.
ÎObservethespeciedtighteningtorques.
Risk of damage to the electric actuator due to incorrect connection of the voltage.
The electric actuator has terminals to retract the stem (eL terminal) and to extend the
stem (aL terminal).
ÎDo not apply a voltage to eL and aL at the same time.
Risk of damage to the electric actuator by turning it too far.
The actuator stem of the electric actuator can be adjusted manually.
ÎOnly retract the actuator stem as far as the end position at the maximum.

3 Design and principle of oper-
ation
ÎSeeFig.3
The pressure-independent control valve
(PICV)consistsoftheType2488Valveand
anelectricactuator.Thevalveisttedwitha
connecting piece for connection of an elec-
tric actuator. As a result, it is possible to
transmit the control signal of an electric con-
trol device to achieve additional temperature
control by changing the restriction position.
Amaximumowratecanbeadjustedme-
chanicallyattherestriction(orice).Theme-
diumowsthroughthevalveinthedirection
indicated by the arrow on the valve body.
Theowrateisdeterminedbytheareare-
leased by the restriction (8.5) and the plug
(3).
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) is transmitted over the control
line (7) to the upstream pressure side of the
actuator. The pressure downstream of the re-
striction acts on the low-pressure side of the
operating diaphragm (6.1) through a hole in
the valve plug. The differential pressure gen-
erated across the restriction is converted into
a positioning force by the operating dia-
phragm. 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 adjuster (8.2).
