Belimo EP050R2+KBAC - 2-way EPIV control valve DN 50

Belimo EP050R2+KBAC – EPIV control valve

2-way control valve with sensor-based flow measurement and control, independent of differential pressure. It is designed for closed-loop water systems and modulating control of the water-side circuits of ventilation and heating systems. If the power supply fails, energy stored in the capacitors moves the valve to the selected safety position.
