The Series BV74 Differential Pressure Balancing Valve is a kind of automatic constant pressure differential balance valve. It's designed to keep constant differential pressure across the supply pipes and return pipes, control valve or terminal unit in airconditioning or heating system. It avoids hydronic disturbances resulting from variations in system differential pressure, achieves dynamic hydraulic balance.
