Bürkert launches range of intelligent valve control heads
23 June 2013
Thanks in part to the popularity of Bürkert’s original 8681 control head that was designed specifically to bring control and connectivity to third party hygienic process valves, Bürkert has now launched three new models in the range.
The 8691, 8685 and 8695 all offer the same connectivity and functionality as the original, but now fit (with model specific adapter kits) a much wider range of valves, including some popular ranges from Bürkert‘s own catalogue.
These smart valve control heads are suitable for a decentralised automation application in a hygienic process environment. They are able to control pneumatic actuation, provide feedback and diagnostic functions plus fieldbus communication.
Larger sized valves can now be controlled using the 8691 control head, extending the scope of the original 8681 while still retaining the high intensity LEDs, AS-i and DeviceNet communications capability.
The new 8695 is targeted at applications in hygienic process environments with a compact design; it is optimised for mounting on Bürkert’s own 21XX process valve series and with smaller actuator sizes.
The control head 8685 is also available with an AS-interface as well as with DeviceNet communication. It can be combined with actuator sizes ELEMENT 50, CLASSIC 40/50/63 or with compact 3rd party process valves. When used in conjunction with the ELEMENT actuators, the unique pilot valve system also enables a compressed air recycling that avoids contamination of the actuator chamber from the local environment.
A stainless steel housing is common throughout the range, as are IP ratings up to IP67.
The indexing of the valve position is performed by a contact-free analogue position sensor, which recognises and saves the valve end position via a 'teach' function on start-up.
