BRUCE kinetic balance electric adjustment valve is a new-generation product distinguishing from traditional kinetic adjustment valve, a product unifying kinetic balance and electric adjustment, and a kind of audiovisual and convenient device controlling flow-rate adjustment. If this valve is applied to network, flow-rate can be directly determined according to design. Valve can automatically slice off the remaining load sell of the pipe under hydraulic effect and the flow-rate deviation caused by pressure fluctuation. The determined flow-rate keeps fixed no matter how system pressure changes. The functions of this valve make adjustment course of network flow-rate needn't to consider the mutual interferences between branch pipes and change flow-rate distribution work into audiovisual onetime operation. It has greatly reduced the amount of work of network technology, and has avoided the flow redistribution operation when shifting and running heat source toward multi-heat source network. This valve not only can remarkably improve the character of heating or cooling, avoid small temperature difference, and run with great flow, but also separately save coal and electricity by1 0 ~ 30%.
