德国哈威单向阀又称止回阀或逆止阀。
用于液压系统中防止油流反向流动,或者用于气动系统中防止压缩空气逆向流动。
单向阀有直通式和直角式两种。
直通式单向阀用螺纹连接安装在管路上。
直角式单向阀有螺纹连接、板式连接和法兰连接三种形式。
液控单向阀也称闭锁阀或保压阀，它与单向阀相同，用以防止油液反向流动。
但在液压回路中需要油流反向流动时又可利用控制油压，打开单向阀，使油流在两个方向都可流动。
液控单向阀采用锥形阀芯，因此密封性能好。
在要求封闭油路时，可用此阀作为油路的单向锁紧而起保压作用。
液控单向阀控制油的泄漏方式有内泄式和外泄式二种。
在油流反向出口无背压的油路中可用内泄式；否则需用外泄式，以降低控制油压力。
HAWE单向阀安装位置HAWE单向阀就是止回阀旋启式止回阀安装位置不受限制，通常安装于水平管路，但也可以安装于垂直管路或倾斜管路上。
HAWE单向阀注意事项安装止回阀时，应特别注意介质流动方向，应使介质正常流动方向与阀体上指示的箭头方向相一致，否则就会截断介质的正常流动。
底阀应安装在水泵吸水管路的底端。
HAWE单向阀关闭时，会在管路中产生水锤压力，严重时会导致阀门、管路或设备的损坏，尤其对于大口管路或高压管路，故应引起止回阀选用者的高度注意。
HAWE单向阀只供防止各类管路或设备上流体介质逆流的单向启闭阀。
公称通径:21/16“~41/16“工作压力：2,000~15,000PSI温度：-60°C~+121°C(K,U)产品规范级别：PSL3~4产品性能级别：PR1~2材料级别：AA~FFHAWE单向阀技术资料下载HAWE单向阀常见故障①阀瓣打碎；②介质倒流。
引起阀瓣打碎的原因HAWE单向阀前后介质压力处于接近平衡而又互相“拉锯”的状态，阀瓣经常与阀座拍打，某些脆性材料（如铸铁、黄铜等）做成的阀瓣就被打碎。

Exception: Valve spools with flow coding 400 do not show control grooves.Indications for angling the lever housing by 180°(inversion of the shifting mode)As set out in 1. - 7. above, however instead of a new valve spool the existing one has to be disconnected, angled at 180° and remounted (see above mentioned note). The in-termediate plate C together with the lever housing, have to be angled at 180°.All lever housings of the valve bank have to be rotated!Lever housing angled at 180°6.3Notes regarding assembly, installation and conversion。

LHDV 型阀专门为那些由于自身弹性而具有强摆动倾向的使用场合设计的。当这种平衡阀与每一个阀块都具有二通进口调节
阀的负载敏感式比例多路换向阀一起使用时将更具有优点。当然，它们应当安装在执行元件和换向阀之间的相应管路上。
作为独立的元件，LHDV 型阀能够有效地介入振动回路，就像这个振动回路是由具有吊挂负载的液压缸、换向阀的流量调节
安装在 V 口周围的任何角度上。在安装面上需一定心凸台，见第 4 节的外形尺寸图。
