As well as the requirements based on the application, the use
of control valves can achieve a longer service life for plant
components. In many cases the continual adjustments of
control valves minimise plant components wear compared to
purely on/off versions.

* Please note that cast bronze valve bodies, when in pipe systems according to DIN are only suitable up to PN 16 max., cast stainless steel bodies
up to PN 25. All pressures are gauge pressures. Min. control pressure for actuators 3 and 4 depends on operating pressure. Kv values determined
acc. to IEC 534 standard, body with threaded sockets DIN ISO 228.
The Kv value data refers to control function 1 (NC) and the largest actuator for each nominal size.
Kv values may be different for other combinations.

* Kv value data with DIN valve body connection. ** Kv value data with ASME-BPE valve body connection.
All pressures are gauge pressures. When the flow is over the seat (M), there may be the danger of water hammer with liquid media! Please note
that cast bronze valve bodies, when in pipe systems according to DIN are only suitable up to PN 16 max., cast stainless steel bodies up to PN 25.
Kv values determined acc. to IEC 534 standard, body with threaded sockets DIN ISO 228. The Kv value data refers to control function 1 (NC) and
the largest actuator for each nominal size. Kv values may be different for other combinations.

you need to control or regulate chemical and physical variables

Manual control                                                      Flow control
Direct local manual operation is the easiest way to exert an
influence on a system with an adjustable valve. The volumetric
flow in a pipe can be set or pre-regulated by a manual valve, e.g.
GEMÜ 507.                                                                                                                GEMÜ 507




Automatic control                                                   Temperature control
The first step in the direction of automation is represented by
the use of a pneumatically controlled valve in connection with a                                                   PLC

Premature wear with             regard     to   cavitation     and
unacceptable noise
Problems may occur in the selection of valves and control
fittings due to cavitation. Damage to the interior valve fitting, the
valve body or the pipe is possible. In addition, loud noise of a
high frequency may occur.
Cavitation is the formation of steam bubbles in liquids. It occurs
when the local static pressure in a liquid drops below the critical
value. This condition can occur, for example, at the constriction
between the valve seat and the regulating cone. If the pressure
rises again after the constriction, the steam bubbles collapse
again, virtually imploding. This creates liquid jets of a high speed
which can cause damage when they hit the interior valve fitting
or the pipe. Molecules are ejected from the surfaces of the
adjacent components. Cavitation causes premature wear and
failure of the components.
In order to prevent cavitation, the exit speed of the liquid at the
valve seat should not be too high. The maximum flow speed
depends on the medium and must therefore be assessed
individually. 20 m/s is often cited as the maximum speed for
liquids in literature. Aerodynamic flow noise due to turbulent
currents in gases may occur in addition to the noise caused by
cavitation. The maximum permissible exit speeds are about 0.6
mach.
In addition to the correct valve design, the course of the pipe
before and after the valve also influences the flow. No bent pipe
sections should be installed directly before and after the valve.
The free outlet distance should be at least 10 times the length
of the valve diameter. As large a pipe nominal size as possible
should be used for the outlet.

available. The combination of electro-pneumatic positioners
and compressed air controlled valves is basically determined
by the control task.
GEMÜ has developed a complete range of positioners for
performing various different control tasks. The electro-
pneumatic positioner range comprises the GEMÜ 1434 μPos,
GEMÜ 1435 ePos and GEMÜ 1436 cPos.
• GEMÜ 1434 μPos - a simple, low cost positioner for single
  acting linear actuators without display and setting keys.
• GEMÜ 1435 ePos and GEMÜ 1436 cPos are positioners for
  use in demanding applications.
  They can be adapted individually to the control task with the
  front keypad and display
• GEMÜ 1436 cPos as a process controller with integrated
  positioner


In addition, the relation between the air output of the positioner,
required control pressure and the size of the valve actuator still
plays a role. This relation determines the valve's operating time.
Depending on the control task and range of the valve, shorter
operating times and therefore higher flow volumes through the
control valves in the positioners are necessary. The GEMÜ 1434
μPos positioner was specially developed for small linear
actuators.
Normally the pilot pressure for a globe valve is controlled in
a positioner and a certain valve opening set as a result. The
GEMÜ 1436 cPos additionally offers an optional process
control circuit for controlling the process. It can be used as a
local process controller and thus relieves the load on the central
control system.
Independently of the correct valve design, the valve must be
positioned with the positioner and the necessary sensors at
the "right place" in the pipe system. Only then is an optimum
function guaranteed. With electro-pneumatic positioners, for
example, generally pressure and flow sensors should always be

In addition to the process parameters and the control system for
which a positioner must be suitable, other technical functions
and properties also play an important part in the selection of the
right positioner.

equipment with the GEMÜ 1436 cPos.
Thanks to the integrated web browser, a user-friendly environ-
ment was created that enables use without software installation,
and it only requires a standard internet browser (Opera,
Windows Explorer, Firefox).
A number of different operating and monitoring possibilities
for programming, evaluation and diagnostics are available to
the user. The integration of graphical analysis in the software
enables the representation of all relevant data for control in real
time curves, supports the user in the exact analysis of his
position and process control and helps him to set the PID
parameters.
In addition, the e.sy-com gives the possibility to download all
parameters of the GEMÜ 1436 cPos as a text file or as a para-

Notes for using standard regulating cones:
1) A tolerance of 10% of full flow is possible for the Kv value               3) It is possible that the selected valves may be able to regulate much

Regulating cones for globe valves

A simple open/close control is not sufficient to exert a flexible
influence on the volumetric flow in a pipe. The volumetric flow
must usually be set precisely to a range adapted to the control
task. For this duty valves are used with regulating cones instead                       Valve
of the conventional valve plugs (diagram A). With increasing                            stroke
opening of the valve, the regulating cone changes the annular                                                               Valve spindle
gap at the valve seat providing a defined control characteristic
(diagram B). A suitable valve, the right regulating cone and a
suitable actuator are necessary for optimum functionality.
Positioners GEMÜ 1434 μPos, GEMÜ 1435 ePos and GEMÜ
1436 cPos are used with actuators for electro-pneumatic
solutions. The stroke or position of the regulating cone is
changed by regulating the control pressure. In motorized solu-
tions, the motor controls this position directly.

GEMÜ globe valves for control tasks are optimised particularly                  Annular gap

Depending on the type of globe valve and the nominal size,
control valve bodies may have widely different geometries.
Regulating ‘needles’ are used for very small nominal sizes and
high pressures because they can control with high precision.
At large nominal sizes, modified regulating cones or regulating

The most frequently used control characteristics are linear and
equal-percentage 1:25 and 1:50. Linear means that the flow
increases linearly with the opening stroke of the valve. The flow
is 50% at the 50% open valve position. This provides good valve
control over the whole stroke range.
The equal-percentage control characteristics have the
                                                                    Kv value %

How to order / Type key

The GEMÜ order system is based on the following type key        the valve body material etc. and then write down the
which enables you to clearly define the products required.       corresponding code number in the given sequence. In order
When you wish to define a valve, first choose the type,           to avoid mistakes we suggest that you insert oblique strokes
the nominal size, the body configuration, the connection,        between the individual numbers.

The Kv value is the flow coefficient of a valve. It is possible to
determine the Kv value of a valve in any opening position. The
Kvs value indicates the maximum flow, this is usually achieved         Basis for calculation for Kv values

The example shows a diaphragm valve with a pneumatic membrane actuator in control function "normally closed" and a manually
operated/lockable diaphragm valve.
In the regulation of volume/mass flow, the measuring element (actual value transmitter) should be positioned before the valve.
In this way the volume flow on the measuring instrument is damped so that the control does not experience sudden measuring step
jumps. The actual value transmitter must be positioned after the valve in pressure and temperature controls.

I controlled systems
An I controlled system exhibits an integral behaviour and has
no compensation. The controlled system does not achieve a
balanced state if the correcting variable is not zero. The
correcting variable changes continuously so that the controlled
variable rises or falls permanently.

Systems with dead zone
In controlled systems with dead zone, the controlled variable
only reacts to the positioning intervention after a certain delay.
This frequently leads to oscillations, especially when the
controlled variable and the correcting variable change
periodically in relation to each other and offset to the dead
zone. Dead zones are usually caused by the process or the
system design (lead times, lag times, positioning of the sensor,
controller and actuator etc.). Many of these influential variables
can be optimised by appropriate system planning for
control-technical requirements. Everything else must be
influenced by an appropriate design of the control circuit.

I controllers
I controllers are integrally acting controllers. A proportional
relation exists between control error and actuating speed.
I controllers are slower than P controllers but eliminate the
control difference completely. The I proportion in a controller
therefore leads to an increase in the accuracy.
The speed of the controller depends on the integral action time
Tn. The greater the integral action time, the slower the controller
responds. This is because the correcting variable y only rises
slowly. If too small an integral action time Tn is selected so that
the controller reaches the given command variable faster,
oscillations may occur.
