TA-Modulator
Pressure independent balancing and control valve for modulating control
The uniquely shaped EQM characteristics provide highly precise temperature control. The valve is compatible with linear, proportional or 3-point actuators. A built-in differential pressure controller provides high control authority, control stability and automatic limitation of design flow. Measurement of flow and available pressure enables system optimisation and diagnostics.
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.
