Control head

for decentral automation of process fittings

Bürkert GmbH & Co. KG

The 8681 control head was specially developed for decentral automation of hygienic seat valves, butterfly valves and ball valves. It supplements Bürkert's ELEMENT series of control heads, digital positioners and process controllers for diaphragm, angle seat and globe valves and rounds out the automation portfolio for the food/beverage and pharmaceutical industries.

The 8681 has been specially optimized 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. 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 hygienic applications. Within the framework of decentral automation concepts the 8681, as a central unit, performs all pneumatic actuation, feedback and diagnostic functions, as well as bus communication. Depending on the process valve, as many as three pneumatic actuator chambers can be controlled separately
