力士乐先导式叠加式减压阀安装在泵出口处或送配水管线中，
用来排除集积在管中的空气，以提高管线及水泵的使用效率，
当管内一旦产生负压时，此阀迅速吸入外界空气，以防止管线因负压而损坏。
　　当管内开始注水时，阀瓣处在开启位置，进行大量排气，当空气排完时，
阀内充满水，浮球上升并带动阀瓣关闭，停止排气，当管内水正常输送时，
如有少量空气聚集在阀内到相当程度，阀内水位下降，浮球随之下降，
，管内水流空或遇管内产生负压，此时塞头迅速开启，吸入空气，确保管线安全。
Operating pressure range Port P bar 20 … 100 for pressure rating 16
Maximum flow P → A or P → B l/min 15 (Δp = 50 bar) see characteristic curves page 7
Hydraulic fluid Mineral oil (HL, HLP) according to DIN 51524
Additional hydraulic fluids upon request!
