External set dynamic flow balancing valve is the combination of the static balancing valve and the dynamic differential pressure balancing valve. It can not only set flow in factory, but also set flow according to the actual flow requirement at installation site. It is especially suitable for each area of heating and air-conditioning system. It has the convenience as the static balancing valve regulates the flow and the accuracy as controlling the flow. It can not only control the maximum flow of the pipeline,but also keep the change relationship of flow and differential pressure suitable for the pipeline characteristics when flow changes.
This valve regulates the maximum flow by regulates the valve opening. Every opening corresponds to a flow value. If the required flow changes because of the late system rectification, we can regulate the opening of the external set dynamic balancing valve to adapt the required flow after rectification. No need to replace the valve, reduce late investment and related costs.
