Rexroth力士乐充液阀A4VSO40DR-PPB13N00节流阀
ND8型则为微处理器（μC）通过改变前置级（PR）线圈的控制电流，前置级阀门降低滑阀（SV）终端的控制压力阀柱向低压方向移动，打开到执行结构气缸顶部的气流，且打开来自活塞另一侧的气流，增加活塞上的差压使活塞移动。微处理器用控制计算一种新的控制电流，直至执行机构的新位置信号与输入信号一致为止。稳定状态下使滑阀（SV）就位，前置级（PR）阀门关闭。能由于智能阀门定位器，是基于微处理器的新一代产品具有高精度的阀门位置信号传感器输出压力传感器等，因而具有较高的控制精度达到（.5—1%），（常规电气阀门定位器精度仅为2—5%），并具有远距离组态，调试，诊断，数据管理等操作。

下面分两方面介绍：权威检测。目前，权威检测，公认的机构只有美电制造商协会（简称：AHAM）。对于通过AHAM检测的空气净化器，把单位面积CADR值（单位面积洁净空气率）按高低排名即可。计算公式为：CADR平均值或单项CADR值认证适用面积1%。权威检测。权威检测分环保系统权威检测和卫生系统权威检测。环保系统检测，因对空气净化率检测前提（条件）还没有统一规定，故先要对检测前提进行了解（各检测机构的检测前提有三个方面不一样：检测实验室空间大小不一样，有1立方米的，1立方米的，3立方米的；污染源的初始浓度不一样，有超3倍的，超5倍的，超8倍的，超1倍的，超1倍以上的；实验净化时间不一样，有3小时的，6小时的，12小时的，24小时的）。
电除尘器优点静电除尘器消耗的能量少，气流压力损失一般为1-5mm水注除尘效率高达9%-99%，运用于去除粒径.5-5微米的尘粒，可用于高温、高压的场合，能持续操作。缺点运行一段时间后除尘效率一路下降电除尘器的运行综合费用高除尘器运行初期，除尘效率基本能达到99%，但由于电厂燃煤品种的变化及电除尘器结构及工作原理的局限，随着运行时间的延续，电除尘器内部组件变形，积灰引起电场变化，除尘效率一路下降，排放严重超标，成为电场的的一块心病；其次，电除尘器的运行综合费用高，电除尘器运行一个周期后，部件结构变形、损坏严重，为保证运行正常，电场不得不经常对除尘器进行维修，维修投入的人力、物力及检修停产带来的损失对电场来说不是一个小数。
