Pressure Independent Control Valves

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.

TB300 allows presetting at the maximum flow, pressure-independent balancing and electric control. Flow control is only related to the opening of the electric actuator, regardless of system pressure differential fluctuation. TB300 valve authority reaches 100%. The actual and ideal flow characteristic curves keep consistent provides precise and fast control, reduces actuator operating frequency, bringing stable energy saving effect.

TS500 allows presetting at the maximum flow, pressure-independent balancing and electric control. Flow control is only related to the opening of the electric actuator, regardless of system pressure differential fluctuation. TS500 valve authority reaches 100%. The actual and ideal flow characteristic curves keep consistent provides precise and fast control, reduces actuator operating frequency, bringing stable energy saving effect.

F535E allows maximum flow presetting, pressure-independent balancing and electric control. The valve is pressure-independent with the built-in piping for easier installation and maintenance. Flow control is only related to the opening of the electric actuator, regardless of system pressure differential fluctuation. F535E valve authority is 100%. The actual and ideal flow characteristic curves is consistent. This helps precise and fast control, reduces operating frequency of the actuator. It gives the pump its optimal flow option, the system is now able to run under minimum flow with the lowest pressure differential, achieving stable, efficient and energy saving effect.
