Retrofit control head enables automation of process valves from any manufacturer
21 July 2013
The advantages of using decentralised process control techniques are well known, however the cost of installing a brand new set of intelligent valves in a production line can be prohibitive.
The answer for many process applications can now be provided by the type 8681 universal control head from Bürkert, which is available with a retrofit kit making it compatible with a huge range of process valves from different manufacturers.
Fitting an intelligent control head or positioner to an existing valve assembly can be far more convenient and faster, reducing both the overall installation time and costs dramatically.
The kit was originally designed so that control heads could be fitted directly to existing valves,thus creating an intelligent valve for a fraction of the cost of a new valve/controller assembly.
Bürkert’s new Type 8681 control head and retrofit kit combination offers universal fitment to third party valve types, including hygienic valves, single seat valves, double seat, mix proof, and also quarter turn ball and butterfly valves that have linear stainless steel actuators.
The 8681 is compatible with a full range of fieldbus communication networks, and is enclosed in a robust housing that is rated to IP67, enabling it to be washed down and cleaned safely.
