ER170 two-way pressure-independent balance valve integrates electric on/off control and pressure-independent balancing. The valve is mainly used for on/off control of cold and hot water in fan coils at the end of the HVAC system and for pressure-independent balancing. In case of pressure fluctuation within the system, it works to keep flow unchanged while the valve is power on, especially in the variable flow system with excessively fluctuating load. It features strong immunity against interference, brings optimal temperature with the best indoor comfort effect.
