SR13 Series FCU Valves

SR13 Series FCU Valves

SR13 series floating/modulating valve is driven by bi-directional motor. The floating /modulating thermostat will continuously collect the data and make processing, and send out control signals to operate or stop the motor so as to control the open/close angle of the valve.
