产品特点及用途PRODUCT CHARACTERISTICS AND USAGE
ZLF-16型自力式平衡阀，是一种利用介质本身的压力变化进行自我控制而保持流经该被控系统流量不变的阀门，并具有流量指示，调节方便，适用于供热空调等非腐蚀性介质的流量控制。运行前一次性调节，即可使系统流量自动恒定在要求的设定值。
This is such a valve as using the self pressure variation to do self control while keep the flow through this controlled system unchanged, with a flow indication, easily adjusted and suitable for the flow control of heat supply, air-conditioning etc. non-corrosive media, Through once adjustment before running can get the system’s flow automatically constant at the required value.
