意大利ATOS比例閥特點: - 可實(shi)現(xian)壓力、速度的(de)無極調節,避(bi)免了常(chang)通的(de)開關式(shi)氣閥(fa)換向時的(de)沖擊現(xian)象。
- 能(neng)實現遠程控(kong)(kong)制和(he)程序控(kong)(kong)制。
- 與(yu)斷續(xu)控制相比(bi),系統簡(jian)化(hua),元件大大減少。
- 與(yu)液壓(ya)(ya)比例閥相比,體積(ji)小、重量輕、結構簡單、成本較低,但響應(ying)速(su)度比液壓(ya)(ya)系統(tong)慢得多(duo),對(dui)負載變化也比較敏感。
- 使用(yong)功率(lv)小、發熱(re)少、噪聲低。
- 不會發生火災,*。受(shou)溫度變化的影響(xiang)小。
