    Handling degassing or viscous media in industrial process cycles requires a configuration built with enhanced valve performance. This Smart Digital S system is engineered with spring-loaded valves to ensure consistent priming and throughput in applications where standard gravity-closed valves may struggle to maintain accuracy.

    Driven by a 24 W motor, the unit delivers a maximum dosing capacity of 30.0 L/h at a 4 bar maximum operating pressure. It utilises a 1000:1 turn-down ratio, allowing the operator to adjust the output from its peak capacity down to 30.0 ml/h, ensuring the hydraulic power of the DDA series is matched with precise volumetric control.

    The hydraulic design utilises advanced stepper motor technology to provide smooth and continuous dosing. The AR control variant includes pulse input, analog 0/4-20mA control, and two potential-free output relays, ensuring the unit can be fully synchronised with complex site process automation.

    Structural durability is ensured by a PVC dosing head and EPDM gaskets paired with ceramic ball valves. Housed in an IP65 enclosure, it handles liquid temperatures to 45°C, is protected against thermal overload by internal electronics, and includes two potential-free output relays for alarm signalling or integration with external control systems.

    FEATURES

    • Spring-loaded valve configuration for optimised performance with viscous or degassing media.
    • AR control variant supports manual, pulse and analog 0/4-20mA operation with potential-free alarm relays.
    • 1000:1 turn-down range from 30.0 L/h down to 30.0 ml/h for precise adjustment.
    • Stepper motor drive technology provides smooth and continuous dosing.
    • PVC dosing head and EPDM gaskets for reliable resistance with non-aggressive chemicals.
    • Internal thermal overload protection for enhanced motor reliability.
    • Two potential-free output relays for alarm signalling or integration with external control systems.
    • IP65 rated enclosure protects internal components from water spray.
