Fascination Bürkert

Welcome to the Fascinating
World of Fluid Control Systems
Measurement and control: When it comes to working with liquids and gases, we are at your side – as a manufacturerof sophisticated products, as a problem-solver with an eye for the big picture, and as a partner offering you reliableadvice. Since we started in 1946, we have developed into one of the world’s leading suppliers of Fluid Control
Systems. At the same time we have kept our status as a family-owned business with a foundation of strong basic
values to highlight the way we think and act.

EXPERIENCE
There are things which are not inherently yours. You have to gather them bit by bit. You receive them from others.
And you constantly have to acquire them anew. That is what makes them so valuable. Experience is one of those
things. For instance, because of our many years of experience with process valves, we can provide our extensive
services to you – from consulting, development, and 3D CAD simulating to testing and after-sales service. Whether individual product solutions or a pioneering new system for the entire control process: Benefit from our experience.

COURAGE
Those who only work toward optimizing things that already exist will eventually reach the limits – technically, financially, or personally. In order to overcome these limits, courage is needed: the courage to be different and trust
one’s own ideas; the courage to venture into the unknown, searching for new ways to develop products that havenever existed before. We have this courage. By pooling and utilizing our competencies across all sectors, you benefit from our cumulative knowledge of valves, actuators, pilots and controllers.

CLOSENESS
There are things we simply take for granted. Only when they are gone, do we realize how important these things
really were. This applies in particular to closeness. Without closeness, it is very difficult to build relationships and agood understanding of one another. As an established medium-sized company, we know that. And that is why weare always there for you. Working with you, we develop the best possible solutions for your projects in the area ofprocess control. Our global presence in 35 locations enables us to press ahead with technical innovations for ourcustomers around the world.

Electromotive actuation – Continuous andOn/Off control
To ensure the best solution for every application and customer need, the modular concept allows any combination of different valve bodies and process interfaces. As high efficiency is extremely important, this concept
has no need of compressed air. That is why it is ideal for mobile applications, where compressed air is limited
or unavailable.
To guarantee flexibility and safety, we provide an adaptable universal actuator for all valve types.

Oxygenthe globe control valve is the standard in many industries.
Bürkert’s idea is to take the standard to a new level in ancompact, light weight envelope. These valves exhibit effective
valve characteristics for continuous variation of the flow as afunction of the parabolic plug position guided by a linear low
friction stem.
Stainless steel or PTFE seals to give either Class IV or ClassVI shutoff and each body size has a range of control plugs
and corresponding replaceable seats for perfect sizing of any

CLASSICThis actuator has been installed around the world in factories and in machines for an extremely
wide variety of duties. It is known universally as the fit and forget actuator which just keeps
going. The actuator is designed to use less energy through the use of clever volume fillers which
do not impede the stroke and lasts longer because of the fact that each actuator part is moldedin house according to our high quality standards and assembled almost completely within robot
cells. The integrity of the inner surface of the cylinder and the flexible N-ring seal are the roots of
the amazing lifespan.
A large range of diameters (40 mm, 50 mm, 63 mm, 80 mm, 100 mm, 125 mm, 175 mm,
225 mm) means that you only invest in what you need. The actuator employs polyamide (PA) for
standard applications and polyphenylsulphone (PPS) for high ambient temperatures or superiorchemical resistance. For applications with high hygienic standards another type of actuator
made completely from stainless steel with smooth surface is also available.

ELEMENTThe ELEMENT actuators combine the engineering excellence of the CLASSIC actuators with afresh new look. Chemical resistance and solid modular connections mix with the beautiful lines
of a stainless steel valve with no external tubes or connections. The ELEMENT actuators are built
to take advantage by internal control air supply so, unlike any other actuator system, each time
the actuator strokes the spring chamber is replenished by clean instrument air. This means:– no corrosion of the actuator springs– no dirt inside the actuator– no humidity transmitted into the control head through the spindle– no biological contamination inside the actuator– longer life
Highly cylindrical, precision molded parts reduce the chances of friction making these actuators
perfect for both On/Off and control duties increasing the availability of fast, accurate control valve
solutions wherever you are in the world.

Pneumatic actuators
Bürkert's pneumatic rotary actuator program is characterized by its versatility and thus offers thepossibility of drawing from a portfolio that has the right actuator for almost any application.

Type 2051 und Type 2052
Pneumatic rotary actuators for rotary valves such as ball valves and butterfly
valves. The helical gear drive principle converts the axial force of the air pressure
into a torque which operates a rotary valve. The intelligent design with low
frictional resistance uses less air than comparable devices, yet provides fast
response times. The connection between actuator and valve is established via
a mechanical universal interface according to ISO 5211. The position of the ballvalve or butterfly valve can in turn be monitored on a control system via a series ofrobust feedback devices (type 1061). For modulating control, the actuator can beperfectly integrated into the Bürkert portfolio of side control positioners (8791/2/3).

The actuators are available in different housing materials and with various coatings
to suit the application.

Type 2051 is available as a pure aluminum actuator. Type 2052 is available both asan aluminium actuator with cataphoretic coating and as a polyamide version.

Type 2053
The 2053 pneumatic actuator enables automated operation of ball valves andbutterfly valves. A linear stroke movement of the actuator piston is converted into
a 90° rotary movement of the actuator shaft. The interface on the valve side isdesigned according to ISO 5211. In addition, the rotary actuator can be combinedwith the ELEMENT actuators and positioners of the Series 8791/2/3/4.
The welded design of the stainless steel housing also makes the actuator 100%
maintenance-free and recommends it especially for hygienic applications. Its slim
design also makes it ideal for space-critical applications.
The air consumption per stroke cycle is very low due to the small cylinder volume.
This ensures a considerable energy saving potential.

Rotary electric
Bürkert’s electrical actuators provide torques to suit many applications from 20 to 100 Nm.
The actuators offer fast rotation times with all standard AC and DC voltages and using rugged
electrical connections. Connection to many types of quarter turn valves is made through the
ISO flange fixation from F03 to F07 with a female star drive adaptor. The actuators deliver both
On/Off and analogue control through signal inputs and outputs of 0/4 - 20 mA and 0 - 10 VDC.

Type 3003
Electric rotary actuator with a torque of 20 - 100Nm.

Type 3004
Electric rotary actuator with Ex protection and a torque of
25 - 300Nm. The manual override on the larger actuatormodels is via a handwheel. Thanks to its IP67 classification,
the actuator is also ideally suited for outdoor applications.

Type 3005
Electric rotary actuator with a torque of 25 - 300Nm. The
manual override on the larger actuator models is via ahandwheel. Thanks to its IP67 classification, the actuator isalso ideally suited for outdoor applications.

Electromotive Actuator
The innovative electromotive linear actuator with fully integrated automation offers a good alternative to traditional pneumatically actuated solutions for applications where highest precision, smart
diagnostics and travel speed programmability, simplicity of design and efficient operation withoutcompressed air counts.
The electromotive linear actuator consists of a brushless direct current motor, gears and a threaded spindle, all put together to form a single unit for fast and easy installation. The valve spindle,
which is connected to the threaded spindle, transfers the force to the control cone.
Valve housing and actuator adaption are identical to our approved pneumatic seat valve program.
As a result, the actuator can be combined with different process valve bodies (DN 15…50) to form
a fully automated electromotive process valve making it even easier for our customer to select aright valve for their application.

Positioners Functional Advantages
A positioner is made from three distinct parts; a displacement transducer for detecting theposition of the valve in its stroke, some control electronics, and finally, a set of valves to supply
or release the pneumatic power.
The pneumatic valves allow air in or out of the actuator according to the desired position. The
displacement measures how far away from the desired position the valve is and the control
electronics determine the amount of air which should be exhausted or added.
For basic operation the positioner only needs a command signal, air and power but these
positioners are packed with lots of time and money saving extras, offer flexible opportunities for
optimizing the function for the application.
Positioner specific valve software functions like close tight cut-off, inversion, free customized
characteristic, start position, and split range provide the perfect collection of advantages.
These functions are selected as needed offering a complete automation concept for integration
into the most up-to-date control systems. All Bürkert positioners are based on the same
operating structure, which unites the features of simple and clear operation.
Designed for tough and agile process environments the positioner’s design optimizes size,
shape and cleanability, footprint and access code security.

Process Controller Functional
Advantages
Process variables such as temperature, pressure, flow rate or level are crucial to processengineering sequences.
The actual process value is detected by means of a suitable sensor in the process and compared tothe process set-point.
Depending on the magnitude and operational sign of control deviation, the process controller
computes the position set-point for the position control loop. The process variable is then changedby opening or closing the valve. Continuous measurement of the actual process value andcomparing it with the process set-point minimizes the control difference between the two values.
Operating structure of the positioners
Inside this small package is an intuitive, fast reliable controller with advanced ProcessTUNE. Add tothis specific valve software functions like close tight cut off, inversion, free customized characteristic,
start position, and split range and you have the perfect collection of advantages.
Distributed intelligence with a clear connection through standard bus protocols, to the coordinationand supervisory level is an important part of the design.

Air Advantages
The ELEMENT range of control heads, positioners and controllers offer four technologicalbreakthoughs which effect the efficiency and lifetime of all the actuators it is coupled with.
Innovative thinking and acting has produced advantages which should easily find their way into
solid engineering specifications as they will be appreciated in the field as they will save headaches,time and investment.
As well as the inherent good looks of the system these four points are tough to overlook.

Housing protected by over pressure
In the housing of types 8690 and 8691 a slight overpressure is controlled via the integrated
air venting valve to prevent ingress of water and accumulation of condensate. Possibly negative
pressure by cold washdown is avoided. Creation and collection of condesate is prevented.
Integrated air inlet filter
An easy to service stainless steel mesh filter protects against the infiltration of bigger particles
after the plant installation und during the normal service. Functional safety and lifetime of theactuator and the actuation are optimised.

Integrated pilot valve
Proven Bürkert pilot valves with outstanding life time are used. Equipped with a manual
actuation the in field operation of the process valve system is easy to handle. It enables theinternal control air routing with compressed air recycling of the actuator.
Compressed air recycling
By internal control air supply via the integrated pilot valve both chambers of the pneumatic
actuator are charged with control air. With every power stroke- open and close- control flushes
from the air vent of the actuation. In no case ambient atmosphere is drawn in the springchamber.
This means:▪ no corrosion of the actautor springs▪ no contamination or humidity inside the actuator▪ from the actuator chambers no humidity gets inside positioner and actuation▪ no contamination of the plant environment by possible biological growth in the actuation chamber

Electromotive On/Off valves withintegrated automation unit
Bürkerts' innovative on/off valves provide an electrically driven process needed for shut-off
operations. An advantage resulting of fully integrated automation is the nonexistent dependence
on a pneumatic system, which leads to low installation and maintenance costs. With its
programmable high travel speed, the electromotive on/off valve closes the gap to pneumatic
solutions. The fast valve opening / closing comes with a soft closing mechanism to avoid hard
impacts on the valve seat and other mechanical parts. On account of the local operation andconfiguration through DIP-switches and pushbuttons under the blind cap, a fast and easycommissioning is guaranteed. To constantly ensure a high plant availability and safety, thediagnostics support informs predictively if there will be a need of maintenance and service in thenear future.
Special about the On/Off valve is the robust housing with superior IP-rating for both indoor andoutdoor use as well as the programmable safety position in case of power failure. By illuminatingby a 360° led, you can get a visible status indication about your device. Furthermore, we make itpossible to indicate your mechanical position at any time, even independently from electricalenergy supply.
The exceptionally fast and dynamic shut-off does virtually not have a delay to the process signal.
To guarantee an extra-long service life, we use durable high quality components only.
