AUTOMATION QUALITY
A robust range of quarter turn valves, all
automation-ready and built to last.
Solenoid valves, process valves,
pneumatics, instruments &
sensors, mass flow control.
Bürkert delivers this complete
range of fluid control
technologies which form the
basis of any process control
system.
Zeroing in on one vital product
group, Bürkert has packaged
Quarter Turn valves and
technologies for modular
simplicity. First dividing quarter
turn into three basic components
– the valve, an actuator and
top works – Bürkert builds a
complete solution. Automationready valves, plus high quality
actuators and unbeatable top
works solutions – a modular,
functional high quality quarter
turn package.
Built with high quality materials,
with smart mechanical
configurations and integrated
network and automation
interfaces, Bürkert’s quarter turn
package fits neatly into the wider
Bürkert product range.

Bürkert Positioners & Process Controllers
Using digital technology, Bürkert’s positioners & process
controllers have pushed through the barriers of traditional
solutions. These positioners are available for linear as well
as quarter turn valves (and other pneumatic devices).
The new range of digital positioners 8791, 8792 & 8793
combine performance, features and a rugged IP65/67
enclosure for field deployment:
- Direct mount interfaces for linear & quarter turn valves
- Remote mount, where valves are in difficult to reach or see
locations (positioner typically wall or cabinet mounted)
The 8791 & 8792 positioners, plus 8793 process controller
are exceptionally rugged and deliver long life service life.
The units share a range of smart features:
n Integrated pilot valve system using filtered recycled
air; no contamination
n Low air usage; no air use at rest position
n One unit for spring return & double acting actuators
n Control up to 150 litres per minute (95…150lN/min)
n Direct mount & remote versions
- Retrofit to other control valves (eg yoke mounted)
n Suitable for all valve sizes; one positioner type for site
- Other pneumatic devices; cylinders, dampers, etc
n One minute, push-button commissioning
Completing the digital positioner package is the 2-wire Type
8635 positioner, with optional process controller for control
loops or DCS. The Type 8635 is approved for hazardous
location deployment and rugged for the most challenging
conditions.
n High quality materials used throughout, compact body
n Network communication interfaces (optional)
n IP65/67 protection & coated aluminium casing for field
deployment in demanding environments

BÜRKERT
Package your process
The Bürkert quarter turn
package has been designed to
systematise the specification
and use of quarter turn valves, as
well as to put them in context of
the wider process. Quarter turn
valves must operate efficiently
within the complete process, as
must all field instruments.
To this end the quarter turn
package reflects the same
high quality materials, smart
mechanical configurations
and integrated network and
automation interfaces as are
found in Bürkert’s complete
range of valves, instruments,
pneumatics and controllers. All
Bürkert products are engineered
to fuse together for tight control
loops, automated processes and
smart turnkey solutions.
With more than 30 years
experience in the Pacific and
65 years worldwide, Bürkert
is a fluid control specialist
maximising on our Germanmanufactured technologies with
local engineering know-how
to deliver results. Contact us
now to see how partnership
with a product manufacturer
and engineering specialist
organisation will support you.

automation of pneumatically controlled hygienic process valves. It is universally adaptable and can be
- Up to 3 pilot valves for actuation
- Contact-free position sensor for switch position feedback
- Process monitoring via optical status indicator
- Communication interfaces
combined with all commercially available valve types, such as butterfly valves, ball valves and single and
double-seat valves. Making it to a universal standard solution for the automation of complete hygienic
process installations. Since the control head is very easy to clean, features time-tested IP protection and
is made of chemical-resistant materials, it is ideal for use in these applications. Within the framework
of decentral automation concepts the 8681 performs all pneumatic actuation, feedback and diagnostic
functions, as well as bus communication. By programmable diagnostic functions specific service functions
may be defined and controlled via the control head.
