THE Burkert type 2731 pneumatically operated diaphragm control valve unites diaphragm technology with a variety of body/seal materials, in nominal diameters 15 to 100 and is particularly suitable for applications with aggressive and abrasive media.
Attachment of the TopControl continuous digital electro-pneumatic positioner produces a powerful control system for critical media. At the press of a button, the Autotune function automatically adapts the TopControl to the valve.
The integrated process controller with PID response can be used as a higher level controller for setting up local closed-loop control systems.
Analogue feedback, binary inputs and outputs and two additional initiators, which can be integrated as limit switches, round out the equipment. The control system can be connected via the TopControl to field bus communication with the Profibus DP and DeviceNet protocols.
