意大利ATOS比例閥特點: - 可實現壓力、速度的(de)無極調(diao)節(jie),避免了常通的(de)開關式氣閥換向時的(de)沖擊現象(xiang)。
- 能(neng)實現遠(yuan)程控(kong)(kong)制和程序控(kong)(kong)制。
- 與斷續控制相比,系統簡化,元件大(da)大(da)減少。
- 與液(ye)壓比(bi)例(li)閥(fa)相比(bi),體積小、重量輕、結構簡單、成本較(jiao)低(di),但響應速(su)度比(bi)液(ye)壓系統慢得多,對(dui)負載變(bian)化也比(bi)較(jiao)敏(min)感。
- 使(shi)用(yong)功(gong)率小、發熱少(shao)、噪聲低。
- 不會發生火災(zai),*。受(shou)溫度變化(hua)的(de)影響(xiang)小。
