Dynamic Differential Pressure Valve

The Series BV74 Differential Pressure Balancing Valve is designed to keep constant differential pressure across the supply pipes and return pipes, control valve or terminal unit in air-conditioning or heating system. It avoids hydronic disturbances resulting from variations insystem differential pressure.
