Belimo EV050R2+BAC - 2-way Energy Valve control valve DN 50

Belimo EV050R2+BAC – Energy Valve DN 50

2-way PI-CCV control valve for closed water systems. Combines a valve with an actuator, a flow sensor and thermal energy measurement. Enables control of flow, power, position and differential pressure; the latter mode requires a differential pressure sensor, which is not included in the scope of delivery.
