General safety instructions
4 The control valves may only be mounted, started up or serviced by fully
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.
4 The control valves fulfill the requirements of the European Pressure Equip-
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.
4 For appropriate operation, make sure that the control valve is only used in
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.
4 Proper shipping and appropriate storage of the control valve are assumed.
Caution!
4 For installation and maintenance, make sure the relevant section of the
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.
4 The electric actuators have been designed for use in electrical power
installations. For wiring and maintenance, you are required to observe the
relevant safety regulations.
4 Only use power interruption devices which are protected against
unintentional reconnection of the power supply.
4 Take special care when making adjustments on live parts. Do not remove
any covers!

Design 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 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.
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 connec-
tion. 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

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

Installation
4 Install a strainer (SAMSON Type 2 NI)
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.
4 The valve must be installed free of stress.
If necessary, support the piping near the
connections.
2
Installation
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.
2.2 Strainer
2.1 Mounting position
4 Install the strainer with the filter element
facing downwards upstream of the valve
inlet.
4 Choose the place of installation where
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 com-
pleted.
4 Choose the place of installation to allow
enough space to remove the filter.
4 Install the strainer with the direction of
flow as indicated by the arrow on the
body.
4 Flush the pipeline thoroughly before in-
stallation.
2.3 Additional installation
instructions
4 Do not install the valve with the actuator
suspended downwards.
Install versions for water and steam up to
200 °C with the actuator installed up-
right in a horizontal pipeline.
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.
4 If you wish to insulate the control valve,
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.

4.1 Type 5757-7 Controller with
Electric Actuator
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.
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 1100/2000 Ω. The
non-floating pump output can alternatively
be used as an binary output for an external
request for heat demand.
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!
The default setting (WE) is configured for an
application with a flow sensor, outdoor sen-
sor and return flow sensor as well as with
an active binary input to switchover the op-
erating modes (see Fig. 2).
4 Perform the electrical wiring as required
depending on the application (refer to
4.2 Type 5757 Controller with
Electric Actuator
As soon as the actuator is connected to the
power supply, the initialization procedure
starts:
Domestic hot water heating in instanta-
neous heating system: The controller with
electric actuator requires a Pt 1000 temper-
ature sensor to be connected for it to func-
tion. Two set points W1 and W2 can be
used for control. A binary input BE1 is used
to switch between them.
In addition, a water flowmeter or a flow
switch can be connected to quickly recog-
nize when hot water is being tapped.
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.
The 0(4) to 20 mA current input can be used
in place of the Pt 1000 sensor for control
purposes.

Maintenance

Maintenance
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.
