哈威EB型插裝節(jié)流閥為嵌入固定節(jié)流孔的插裝節(jié)流閥。哈威EB型插裝節(jié)流閥的工作壓力Pmax=500bar和流量Qmax=120L/min。主要用于對切換過程進行流量限制（例如：防止從先導(dǎo)閥引來過大流量；在蓄能器切換油路上，防止由于負遮蓋方向閥切換時引起不應(yīng)有的卸壓等等），對安裝在油路塊上的液壓閥而言，事先嵌入閥內(nèi)。

哈威EB型節(jié)流閥，HAWE哈威插裝節(jié)流閥，哈威EB型插裝節(jié)流閥的技術(shù)參數(shù)：
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.
