2. 特性
压力作用下使得流体从1流向2 ，而液体从2流向1时则反向密封，油液无法通过
通过90º锥阀芯和合成材料的密封环与锥阀座配合实现密封，阀芯开启具有定位，因此开启可靠，振动小，噪音低，阀体流通截面均匀。推荐的最大流速不超过8米/秒
2.1 开启压力：标准开启压力为0.5bar ，可提供 0.2，0.7，1 ，2 ，3 ，4， 5 ，6，7 bar，允许在+-20%内变化
2.2理想工作温度：NBR:-20°C～+90°C/ FKM :-5°C～+180°C/HNBR:-40°C～+120°C
2.3安装扭矩：参考4.参数里的扭矩说明，注：本体材料为碳钢，拧入件为钢件， 其他材料请联系auer工程师
2.4油液清洁度：ISO4406：1999标准4μm/6μm/14μm 19/17/14
2.5 auer提供阻尼单向阀，阻尼孔尺寸请联系auer工程师
