Filter, clean, rinse

The filtering station filters liquids. The filtrate is pumped from the first tank through the filter via a slide valve. The filtered liquid enters the second tank via the flap with pneumatic swivel drive. The filtered liquid can be pumped on to the next station using a separate pump. The filter can be backwashed with a rinsing program. To loosen deposits, the filter is also blown free with regulated compressed air.

Measuring, controlling and regulating
Sensors record the tank fill levels in the filter station. This allows simple control tasks for monitoring the pumps, through to complete control projects for complex process operations in the classroom.

The pressure control ensures consistently high filter quality during backwashing. The pressure sensor with LCD display, analog output and switching output always provides the correct measured variable. Via the proportional pressure control valve, the controller with P, PI or PID control algorithm ensures consistently high filter quality during backwashing. This provides clear and practical training in control technology.

Shut off, open, close
In complex process sequences, the correct selection of process valve, actuator, actuator accessories and control valve plays a decisive role. A wide variety of process components are used at the filter station. All valve actuators are controlled via a directly flange-mounted NAMUR valve.
