Features and 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.
Applications
Heating and cooling systems.
