Belimo EV020R2+BAC - 2-way Energy Valve control valve DN 20

Belimo EV020R2+BAC – Energy Valve DN 20

2-way control valve with actuator, flow sensor and thermal energy meter. Designed for closed water systems and modulating control of air-conditioning and heating systems on the water side. Enables control of flow, power, position or differential pressure; differential-pressure control mode requires a sensor, which is not included.
