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. Automation-ready 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.

BÜRKERTPackage 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 German-manufactured technologies with local engineering know-how to deliver results.

With our control head 8681 a new star is born! With the 8681 Bürkert presents a new control head which has been specially optimised for decentral

automation of pneumatically controlled hygienic process valves. It is universally adaptable and can be

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.

Decentral automation completed

The universally adaptable Control Head 8681 completes

the ELEMENT valve product range with an integrated

automation function for the control of auxiliary circuits like

steam, pressurised air or cleaning agents. With this all the

advantages of a decentral automation as an alternative to

cabinet solutions can be used for all armatures. Process

monitoring, minimal installation effort for electrical wiring

and pneumatic tubing when using the AS-interface.

Flexibility during planning and clear plant construction for

plant hygienic, energy saving by minimal compressed air

consumption and shortest switching times.

Wireless is also possible

Parametrisation and configuration are done via Bluetooth

or USB-interface. A device remote control, teach-in and

activation of the autotune-function is possible. Furthermore,

diagnostic functions are read and edited or device data as

software version and bus specific parameters are shown.

Easy installation, operation and status control

The automated teach-function of the switching positions

replaces manual setting work and guarantees function

safety. The switching speed can be set individually in

each direction and in terms of the absolute process safety

pneumatic check valves prevent switching errors due to

back pressure. Additionally to the control layer the valve

status of the plant is clearly shown via coloured status

indication.

Maintenance function process valve

A maintenance demand programmed via limit value

for switching cycles and operating hours is shown via

the blinking status indication. Thanks to a the patented

magnetically encoded manual override tool the actuator can

be used to open the process valve from the exterior. The IP

protection is guaranteed every time.
