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.
