The electropneumatic positioning system for control accuracy and dynamics, remains the same on the SideControl 8791 and it can be mounted in various different ways to linear and rotary actuators according to IEC534-6 and VDI/VDE 3845 (Namur) as well as to Bürkert process valves. The SideControl 8791 is flexible and suitable for a wide range of applications and for use in harsh environments due to its compact, sturdy aluminium housing with protection class IP65/67.

As there is no display and the software has been simplified, the SideControl 8791 positioner is a good alternative for applications where no further configuration on site is necessary. The only controls on the device are used to call up preset values. Other parameters for the positioner can be configured from a PC connected via the RS232 interface, using PACTware.

The SideControl 8791 from Bürkert uses 3-wire technology and is approved for ATEX zones 2/22. The Bürkert SideControl 8791 positioner can be used as the sole positioning system for the entire compressed air supply, directly from the network and without costly pressure reduction. The positioning system of the SideControl 8791 features an control air pressure range of 1.4 to 7 bar and a high air power range of 7 to 100 l/min (150 l/min at 6 bar). When fully regulated, no control air is consumed.
