　　NIBCO's new Circuit Balancing Valves control and maintain a comfortable indoor climate while saving energy and reducing costs. These control valves ensure trouble-free operation and ease of maintenance.

　　为什么能够平衡您的系统？
　　Why Balance Your System?
　　无论一个系统是用于供热、制冷或给排水，都必须进行恰当地调节和平衡，达到最优的设计性能。一个不能平衡的系统，在各个房间之间可能造成7^oC的温差，这会造成35%的能源浪费。
　　Whether a system is designed for heating, cooling or water distribution, it must be properly adjusted and balanced for optimum design performance. An unbalanced system may produce temperature variations of up to 14^oF between rooms, which can add up to 35% to energy costs.
