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

Belimo EP050R2+BAC control valve

EPIV is a 2-way control valve with an actuator and flow sensor. The measured flow is compared with the setpoint, and the actuator adjusts the valve position. The device is intended for closed-loop water systems and modulating control of ventilation and heating systems on the water side.
