哈威EB型插装节流阀为嵌入固定节流孔的插装节流阀。哈威EB型插装节流阀的工作压力Pmax=500bar和流量Qmax=120L/min。主要用于对切换过程进行流量限制（例如：防止从先导阀引来过大流量；在蓄能器切换油路上，防止由于负遮盖方向阀切换时引起不应有的卸压等等），对安装在油路块上的液压阀而言，事先嵌入阀内。

哈威EB型节流阀，HAWE哈威插装节流阀，哈威EB型插装节流阀的技术参数：

The orifice inserts type EB are part of the flow valves, whereas the restrictor check  valves type BE and BC are a combination of a flow and check valve.  These valves are preferentially used to limit flows when switching directional  valves （e.g. flow limitation to Qmax and avoidance of excessively rapid accumulator draining）. The restrictor check valves type BC and BE are designed as a hole or  slot orifice and enable free flow in the direction F → B and throttle function in the  opposite direction.  Type BC is spring loaded and can be screwed into normal threaded holes （point angle  118°）.  Type EB orifice inserts can be used in the P gallery of manifold mounting valves, for  example.
