意大利ATOS比例閥特點： - 可(ke)實(shi)現壓力、速度的(de)無極調節，避免了常(chang)通的(de)開關式氣閥換向時的(de)沖擊現象(xiang)。
- 能實現(xian)遠程控(kong)制和(he)程序(xu)控(kong)制。
- 與斷續控制(zhi)相比，系統簡化，元件大大減少。
- 與液壓(ya)比(bi)例閥相比(bi)，體積小、重量輕、結構簡(jian)單、成本(ben)較低，但響(xiang)應(ying)速度比(bi)液壓(ya)系統慢得多(duo)，對負載變化也比(bi)較敏感。
- 使(shi)用功率小(xiao)、發熱(re)少、噪聲(sheng)低。
- 不(bu)會發生火災，*。受溫度變化(hua)的影響小。
