Belimo EP125F2-25+BAC - 2-way EPIV control valve

Belimo EP125F2-25+BAC

2-way EPIV control valve for closed water systems. The sensor measures the flow rate, and the actuator adjusts the valve position in relation to the setpoint. The device is designed for modulating control of water-side heating and ventilation systems.
