液压阀外壳
这一切都取决于主孔。阀门外壳的制造是流体技术领域的“最高学科”。多年来，对MAPAL公司在滑块钻孔方面的专业知识的需求一直很高。与滑块的间隙尺寸取决于该孔的精度，因此液压油只能无泄漏地沿着所需方向流动。现代液压阀对该尺寸的定义非常狭窄。因此，非常重视该孔的圆度、圆柱形状、直线度和表面质量。
加工要求
- 波动的铸铁加工余情况
- 超强中断的切削口
- 镗孔时避免环圈的形成，并确保从外壳中安全排出切屑
- 避免在镗孔流程中控制刃口上出现破裂现象
- 对形状和位置公差的要求非常高
- 珩磨之前的恒定加工余量
- 在切削加工方案中考虑组件差异和有限的刀具储存器位置
方向控制阀
方向控制阀是具有多个开关位置的采用机械或电子方式操作的阀门。根据控制滑块沿着控制刃口的指定位置，设置体积流量以运行连接的机具。独立压力天平（IDW）调节控制滑块流入控制刃口上的恒定负载压力梯度，从而在整个调节范围内实现独立于负载压力的体积流量控制，即使在并联运行（负载补偿）时亦是如此。系统必须无泄漏，以防止负载意外下降，即使在并联运行时亦是如此。
