項目要用氣動(dòng)缸來(lái)做升降，要求下降時(shí)是電磁閥動(dòng)作時(shí)就下降，中間要求停留比較穩定，要求電源關(guān)斷后還能保持停留在中間狀態(tài)，下次通電后繼續按當前狀態(tài)動(dòng)作。
前輩們有什么比較成熟的經(jīng)驗，指導下��！不勝感激！好像用三位鎖定型五通閥加SMC的先導式單向閥速度控制閥能有比較好的類(lèi)似功能，但不太好找！

停止位置精度和可靠性要求高的話(huà)可考慮使用電缸，象伺服或機械手一樣的控制，體積比較小，停止位置精準，就是成本要高點(diǎn)。用帶鎖定型的氣缸停止位置精度要求不高的話(huà)可考慮（鎖定的停止位置與氣壓調節的高低關(guān)系很大）。
天下事有難易乎？為之，則難者亦易矣！不為，則易者亦難矣！
