The differential pressure bypass valve can maintain the pressure difference of the flow through the centrifugal pump. No matter how the upstream supply or the downstream demand changes, the pressure difference can always be maintained within a certain range. By controlling the pressure difference across the centrifugal pump, the flow of the pump can be controlled.
Install the W817/W837 differential pressure bypass valve in the circulating water system, as shown in the figure. It can ensure the pressure difference between the supply pipe and the return pipe, and no matter how the flow changes, how the supply pressure changes, the pressure difference between the two pipes is constant.
