意大利ATOS比例閥特點: - 可實(shi)現(xian)壓力、速度的無極調節,避免(mian)了常通的開關(guan)式(shi)氣閥換向時的沖(chong)擊現(xian)象。
- 能實(shi)現遠程控制和程序控制。
- 與斷續(xu)控制相比,系統簡化,元件(jian)大(da)大(da)減少。
- 與液壓比(bi)(bi)例閥相比(bi)(bi),體積(ji)小(xiao)、重量(liang)輕(qing)、結構簡單、成本較低,但響應速度比(bi)(bi)液壓系統慢得多(duo),對負載變(bian)化也比(bi)(bi)較敏感。
- 使用功率小、發熱(re)少、噪(zao)聲低。
- 不會發生火災,*。受溫度變化的影響小。
