LS WS series of 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.
