Positioner (for control valve)

The positioners for control valves come in various lineups for each function. They are designed for energy efficiency with solenoid valve control rather than diaphragm control, resulting in zero bleed air! ■Type 8692【Smart positioner with standard LCD】 ■Type 8693【Type 8692 equipped with process controller (PID, etc.)】 ■Type 8792【Separated version】 ■Type 8793【Separated version + equipped with process controller】 In addition to these, explosion-proof specifications (increased safety explosion-proof) are also available. Furthermore, Burkert is a rare company that fully designs both valves and positioners in-house. This is why it has the following features: - Linearization function before tuning the regulator → Enables linearization of signal and flow, rather than opening degree and flow (PQLIN function within the process controller) - EHEDGE-compliant design as a control valve - Unified design and exterior materials - Cut-off function → Understanding that the behavior near the zero point of the control valve is unstable, this function forcibly closes the valve with a setpoint signal below a certain threshold.
