General safety instructions
General safety instructions
The control valves may only be mounted, started up or serviced by fully
4
trained and qualified personnel, observing the accepted industry codes and
practices. Make sure employees or third persons are not exposed to any
danger.
All safety instructions and warnings in these mounting and operating
instructions, particularly those concerning assembly, start-up and
maintenance, must be observed.
The control valves fulfill the requirements of the European Pressure Equip
4
ment Directive 97/23/EC. Valves with a CE marking have a declaration of
conformity which includes information about the applied conformity assess
ment procedure. The declaration of conformity is available on request.
For appropriate operation, make sure that the control valve is only used in
4
applications where the operating pressure and temperature do not exceed
the operating values which are based on the valve sizing data submitted in
the order.
The manufacturer does not assume any responsibility for damage caused by
external forces or any other external influence!
Any hazards which could be caused in the control valve by the process
medium, the operating pressure, the signal pressure or by moving parts are
to be prevented by means of the appropriate measures.
Proper shipping and appropriate storage of the control valve are assumed.

Caution!
For installation and maintenance, make sure the relevant section of the
4
pipeline is depressurized and, depending on the process medium, drained
as well. If necessary, allow the control valve to cool down or warm up to
reach ambient temperature prior to starting any work on the valve.
The electric actuators have been designed for use in electrical power
4
installations. For wiring and maintenance, you are required to observe the
relevant safety regulations.
Only use power interruption devices which are protected against
4
unintentional reconnection of the power supply.
Take special care when making adjustments on live parts. Do not remove
4
any covers!

Design and principle of operation
1Design and principle of
operation
The control valves consist of a single-seated
Type 3222 Globe Valve and either a
Type 5757, Type 5757-7 or Type 5724
Controller with Electric Actuator or a Type
5725 Controller with Electric Actuator with
safety function.
The process medium flows through the globe
valve in the direction indicated by the arrow
on the body. The position of the valve plug
determines the flow rate over the cross-sec
tional area of flow released between the
plug (3) and valve seat (2). The plug stem
(4) with plug is connected with the stem of
the actuator (10) by a force-locking connection. The valve is opened by the valve spring
(5) following the retracting movement of the
actuator stem. A special version is required
for water above 150 °C and for steam
(Fig. 1). The plug is moved by a change in
the control signal acting on the actuator.
The electric actuator with safety function
(Type 5725) has a spring mechanism and
an electromagnet that can be connected to a
safety control circuit. When the control cir
cuit is interrupted or the power supply fails,
the magnet disengages the gear from the
self-locking motor and releases the spring
mechanism. The valve is closed in the event
of a safety situation (fail-safe action
“actuator stem extends”).
The electric actuators contain a digital con
troller integrated into the actuator. The con
trolled variable is recorded over the directly
connected Pt 1000 sensor (see Table 2).
The output signal of the digital controller
acts as a three-point stepping signal on the
-
-
-
synchronous motor of the actuator and is
transferred over the connected gear as a
positioning force onto the actuator stem.
The Type 5757, Type 5724 and Type 5725
are particularly suitable for DHW heating in
instantaneous heating systems and for fixed
set point control circuits in mechanical engi
neering applications.
Type 5757-7 is suitable for heating applica
tions.

2Installation
Caution!
Versions designed to handle temperatures
up to 200 °C must be fitted with the dark
gray graphite supplied with the valve. Do
not use the UDP seals available as accesso
ries as they are only suitable for tempera
tures up to 150 °C.
-
Installation
Install a strainer (SAMSON Type 2 NI)
4
upstream of the control valve to prevent
any sealing parts, weld spatter or other
foreign matter carried along by the pro
cess medium from impairing the proper
functioning of the valve, in particular, the
-
tight shut-off.
The valve must be installed free of stress.
4
If necessary, support the piping near the
connections.
-
2.1Mounting position
Choose the place of installation where
4
the ambient temperature does not ex
ceed or fall below the permissible limits
specified for the actuator and that allows
you to freely access the control valve
even after the entire plant has been completed.
Flush the pipeline thoroughly before in-
4
stallation.
Do not install the valve with the actuator
4
suspended downwards.
Install versions for water and steam up to
200 °C with the actuator installed up
right in a horizontal pipeline.
If you wish to insulate the control valve,
4
install an intermediate insulating piece
between valve and actuator. Make sure
the insulation ends 25 mm above the
valve body. Do not insulate the actuator
and coupling nut as well.
2.2Strainer
Install the strainer with the filter element
4
-
facing downwards upstream of the valve
inlet.
Choose the place of installation to allow
4
enough space to remove the filter.
Install the strainer with the direction of
4
flow as indicated by the arrow on the
body.
2.3Additional installation
instructions
-
We recommend to install a hand-operated
shut-off valve both upstream of the strainer
and downstream of the control valve to be
able to shut down the plant for cleaning and
maintenance, and when the plant is not
used for longer periods of time.

Electrical connections
4Electrical connections
Upon installing the electrical cables,
you are required to observe the regula
tions concerning electrical power in
stallations according to DIN VDE 0100
as well as the regulations of your local
power supplier.
Use a suitable power supply to ensure
that no dangerous voltages from the
system or parts of the system reach the
device in standard operation or in case
of a fault.
Warning!
Only connect the device to the main
power network when the power is
switched off. Make sure the power
cannot be switched on unintentionally!
Perform the electrical wiring as required
4
depending on the application (refer to
section 4.1 to 4.3).
As soon as the actuator is connected to the
power supply, the initialization procedure
starts:
The actuator stem extends and the red and
yellow LEDs located under the cover on top
of the actuator light up. As soon as the actu
ator stem has reached the final position, the
red LED is turned off. The yellow LED re
mains illuminated and indicates that the
controller with electric actuator is ready for
operation.
4.1Type 5757-7 Controller with
Electric Actuator
Heating application: The controller with
-
electric actuator requires a Pt 1000 temper
-
ature sensor to be connected to measure the
flow temperature. Depending on the control
task, an outdoor sensor or a room sensor or
a room panel can be connected. Combining
one of these sensors with a return flow sen
sor is usually possible. Additionally, the con
troller with electric actuator has a potenti
ometer input 1000 to 1100/2000Ω. The
non-floating pump output can alternatively
be used as an binary output for an external
request for heat demand.
The default setting (WE) is configured for an
application with a flow sensor, outdoor sensor and return flow sensor as well as with
an active binary input to switchover the operating modes (see Fig. 2).

The control valve is subject to natural wear.
Depending on the conditions the valve is op
erated in, it needs to be checked at regular
intervals.
If leakage to the atmosphere occurs, remove
the valve from the pipeline and replace the
damaged parts.
Warning!
For maintenance work on the valve,
make sure the relevant section of the
pipeline is depressurized and,
depending on the process medium,
drained as well.
For high medium temperatures, allow
the section of the pipeline to cool down
before you start.
Make sure the control signal for the
actuator is switched off.
