意大利ATOS比例閥特點: - 可實(shi)現壓力(li)、速(su)度的(de)無極調節,避(bi)免(mian)了常通的(de)開(kai)關(guan)式氣閥換(huan)向時的(de)沖擊現象。
- 能實(shi)現遠程控制(zhi)和程序控制(zhi)。
- 與(yu)斷續(xu)控制相比,系統(tong)簡化,元件大大減少。
- 與(yu)液壓比(bi)例閥相比(bi),體積小、重量輕、結構簡單、成本較低,但響應速(su)度比(bi)液壓系統慢得(de)多(duo),對負載變化(hua)也比(bi)較敏(min)感。
- 使用功率小、發熱(re)少、噪聲低。
- 不會發生(sheng)火災,*。受溫度變化的(de)影(ying)響小。
