W-DPBV-16/25Q 系列(DN200-DN250)

Dynamic differential pressure balancing valve, also known as differential pressure controller, is a balancing valve that can automatically keep the constant differential pressure. it is used for keeping 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 from variations in system differential pressure and to achieve the dynamic hydraulic balance.
