意大利ATOS比例閥特點： - 可實現壓力、速度的(de)(de)無(wu)極調節，避(bi)免了常通的(de)(de)開關式氣閥換向時的(de)(de)沖擊(ji)現象。
- 能(neng)實現遠程控制和程序控制。
- 與斷續控制相(xiang)比，系統簡(jian)化(hua)，元件(jian)大大減少。
- 與液壓比(bi)(bi)例閥相比(bi)(bi)，體積小(xiao)、重量輕、結構(gou)簡(jian)單、成本(ben)較(jiao)低，但響應速度比(bi)(bi)液壓系統慢得(de)多(duo)，對負載(zai)變化(hua)也比(bi)(bi)較(jiao)敏感。
- 使用功(gong)率小(xiao)、發熱(re)少、噪聲低(di)。
- 不會發生火災，*。受溫度(du)變化(hua)的影響(xiang)小。
