General safety instructions

1 General safety instructions

For your own safety, follow these instructions concerning the mounting, start up and opera
tion of the control valve:

The control valves must be installed, started up and serviced by fully trained and qualified

4

personnel only, 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 installation, start-up and maintenance, must be observed.

For appropriate operation, make sure that the control valve is only used in applications

4

where the operating pressure and temperatures do not exceed the operating values
based on the sizing data submitted in the order.
Note that the manufacturer does not assume any responsibility for damage caused by
external forces or any other external factors.
Any hazards which could be caused in the control valve by the process medium or
operating pressure are to be prevented by means of appropriate measures.

For installation and maintenance, make sure the relevant section of the pipeline is

4

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 it.

The actuators are designed for use in low voltage installations.

4

For wiring and maintenance, you are required to observe the relevant safety regulations.
Take necessary measures to ensure that the power supply cannot be reconnected inadver-

4

tently.
Take care while performing adjustment work on live parts. Never remove any covers!

4

-

To avoid damage to any equipment, the following also applies:

Proper shipping and appropriate storage are assumed.

4

Note: The control valves fulfill the requirements of the European Pressure Equipment Directive
97/23/EC. Valves with a CE marking have a declaration of conformity which includes infor
mation about the applied conformity assessment procedure. The declaration is available on
request.

2 Design and principle of

operation

The actuator in the three-point stepping ver
sion consists of a reversible synchronous
motor and a maintenance-free gear.

The version with digital positioner contains a
stepper motor which can be supplied with
any voltage regardless of the frequency.

Actuator and valve are connected (force­locking) over a coupling nut (6). An interme
diate insulating piece can be used for insu
lated pipelines.

The medium flows through the single-seated
globe valve in the direction indicated by the
arrow. The position of the plug (3) deter­mines the flow rate across the area released
between plug and valve seat (2).

The linear actuating force is transmitted di­rectly over the actuator stem (7) to the plug
stem (5). When the actuator stem extends,
the valve plug (3) moves in the closing direc­tion. The plug stem follows the actuator stem
owing to the force of the valve spring (4) as
the actuator stem retracts, causing the valve
to open.

Installation

3 Installation

If the valve and actuator are delivered sepa
rately, first install the valve in the pipeline
and then mount the actuator.

3.1 Mounting 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 com
pleted.
Flush the pipeline thoroughly before in-

4

stallation.
Never install the valve with the actuator

4

suspended downwards.
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 pro­cess 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.

3.3 Additional 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.

3.2 Strainer

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 flow direction

4

as indicated by the arrow on the body.

NOTICE

The handwheel is used to move the actuator
stem. Only operate the handwheel when the

actuator is in the de-energized state.

In the version with digital positioner, do not op
erate the handwheel while the actuator is in ser­vice (absolute travel adjustment, see
EB 5857 EN), otherwise the feedback signal will
be shifted.

4.2 Mounting the actuator on the

4.3 Electrical connection

DANGER!
Risk of electric shock!

When installing electric cables, you are
required to observe the regulations
governing electrical power plant
installation according to
DIN VDE 0100 as well as the
regulations of your local power supply
company.
Use a suitable power supply which
guarantees that no dangerous voltages

-

reach the device in normal operation
or in case of a fault in the system or
any other system parts.
Connect the actuator to the electrical
network only after the power supply is
first switched off. Make sure the power
cannot be switched on unintentionally!
Especially when a 24 V voltage supply
is used, wires with sufficiently large
wire cross-sections must be used to
guarantee that the permissible voltage
tolerances of

10 % are not exceeded!

±

1. Turn the handwheel (Fig. 2) counter

-

clockwise only after disconnecting the
actuator from the power supply to re
tract the actuator stem as far as it will
go.

2. Place the actuator on the valve connec

tion or the intermediate insulating piece
and secure with the coupling nut (tight
ening torque 20 Nm).

Three-point stepping version

Connect the cable as shown in Fig. 3,

4

observing the following instructions.

The control signals of the connected con
troller are connected to the terminals eL
and aL:

If a voltage is applied to eL, the ac

4

tuator stem retracts into the actuator
(direction of action ”Stem retracts“).
If a voltage is applied to aL, the ac

4

tuator stem extends out of the actua
tor (direction of action “Stem ex
tends“).

Important note:

Decoupling capacitors Ce in the output

4

circuit of the connected controller may
not exceed a value of 2.5 nF in order to
guarantee the proper functioning of the
actuator.

WARNING!

Directly after connecting the voltage to the
actuator, a zero calibration is automatically
performed when the absolute travel adjust

­ment is set (state of delivery), causing the
actuator stem to move.
Do not touch the actuator stem or obstruct it
to avoid risk of injury to hands or fingers.

NOTICE

During zero calibration, the control valve
moves through a part of the travel range.
As a result, do not connect the wires of the
actuator while a process is running. Instead,
close the shut-off valves in the plant first.

5 Maintenance

WARNING!

For maintenance work on the valve, make
sure the relevant section of the pipeline is
depressurized and, depending on the pro
cess 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.

The control valve is subject to natural wear.
Depending on the conditions the valve is op­erated in, it needs to be checked at regular
intervals.
If leakage to the atmosphere occurs, disas­semble the valve and replace the damaged
parts.
