Features & Benefits

    Precise temperature control

    Provide uniquely shaped EQM characteristic for best modulating control.

    Precise control

    Uniquely shaped EQM characteristic provides an up to 6 times larger operating stroke than linear valves.

    Quick hydronic balancing

    Automatic flow limitation when actuator is fully open protects entire system against overflows.

    Easy troubleshooting

    Flow and differential pressure measuring helps to reduce pump consumption and provides all necessary data for system diagnostics.

    Technical description

    (Valid for maximum setting, fully open. Other settings will require lower differential pressure, check with the software HySelect.)

    ΔpVmax = The maximum allowed pressure drop over the valve to fulfill all stated performances.

    ΔpVmin = The minimum recommended pressure drop over the valve, for proper differential pressure control.
