Differential Pressure Balancing Valve

The Series SDP 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 hydraulic disturbances resulting from variations in system differential pressure.
