意大利ATOS比例閥特點: - 可實(shi)現(xian)(xian)壓力、速(su)度的無(wu)極調節,避(bi)免了常通(tong)的開關式氣(qi)閥換向時的沖擊(ji)現(xian)(xian)象。
- 能(neng)實現遠(yuan)程控(kong)制和程序控(kong)制。
- 與(yu)斷續控制(zhi)相比,系統簡化,元件大大減少。
- 與液壓比(bi)(bi)例閥(fa)相比(bi)(bi),體(ti)積小(xiao)、重量輕、結構(gou)簡單、成本較(jiao)低,但(dan)響應速(su)度(du)比(bi)(bi)液壓系統慢(man)得多,對負載(zai)變化也比(bi)(bi)較(jiao)敏感(gan)。
- 使(shi)用功(gong)率小(xiao)、發熱少(shao)、噪聲低。
- 不會發生火災,*。受溫度變(bian)化的影響小。
