TA-FUSION-C

These innovative balancing and control valves for heating and cooling systems combine the key hydronic functions of balancing and control in one valve. Adjustable Kvs and inherent independent EQM characteristics allow correct valve sizing and optimum system controllability. The measuring points enable accurate measurement of flow, differential pressure, temperature and available differential pressure.

Product Information

Combined balancing and control valves with independent EQM characteristics

These innovative balancing and control valves for heating and cooling systems combine the key hydronic functions of balancing and control in one valve. Adjustable Kvs and inherent independent EQM characteristics allow correct valve sizing and optimum system controllability. The measuring points enable accurate measurement of flow, differential pressure, temperature and available differential pressure.

Key features

Adjustable Kvs

Allows correct Kvs setting corresponding to system requirements.

Independent, inherent EQM characteristic

Proper EQM valve characteristic for all settings.

Self-sealing measuring points

Simple and accurate measurement for balancing, trouble shooting and power measurement.

Actuators

Valves and actuators supplied together ensuring optimum control performance and simplified selection.
