低價*原裝德國力士樂比例伺服閥

     REXROTH力士樂比例閥其實缺點極多：能耗浪費大、容易出故障、抗污染能力差、價格昂貴等等等等，好處只有一個：動態性能是所有液壓閥中zui高的。就憑著這一個優點，在很多對動態特性要求高的場合不得不使用伺服閥，如飛機火箭的舵機控制、汽輪機調速等等。動態要求低一點的，基本上都是比例閥的天下了。

    一般說來，好像伺(si)(si)(si)(si)服(fu)(fu)(fu)系統都(dou)是閉環控(kong)制(zhi)(zhi)，比(bi)(bi)例多用于開環控(kong)制(zhi)(zhi)；其次比(bi)(bi)例閥類型要(yao)多，有比(bi)(bi)例壓力(li)、流(liu)量控(kong)制(zhi)(zhi)閥等(deng)，控(kong)制(zhi)(zhi)比(bi)(bi)伺(si)(si)(si)(si)服(fu)(fu)(fu)藥靈(ling)活一些(xie)。從(cong)他們內部結構看，伺(si)(si)(si)(si)服(fu)(fu)(fu)閥多是零遮蓋，比(bi)(bi)例閥則有一定的死區，控(kong)制(zhi)(zhi)精度要(yao)低(di)，向應要(yao)慢(man)。但從(cong)發展(zhan)趨勢看，特(te)別在比(bi)(bi)例方向流(liu)量控(kong)制(zhi)(zhi)閥和伺(si)(si)(si)(si)服(fu)(fu)(fu)閥方面(mian)，兩者(zhe)性能差別逐漸在縮小，另(ling)外比(bi)(bi)例閥的成本比(bi)(bi)伺(si)(si)(si)(si)服(fu)(fu)(fu)閥要(yao)低(di)許多，抗污染能力(li)也強！
