意大利ATOS比例閥特點: - 可實現壓力、速度的(de)無(wu)極調節,避免(mian)了(le)常通的(de)開關式氣(qi)閥換向(xiang)時的(de)沖擊現象。
- 能實現遠程(cheng)控制和程(cheng)序(xu)控制。
- 與斷(duan)續控制相(xiang)比(bi),系統簡化,元件大大減(jian)少。
- 與(yu)液壓(ya)比(bi)(bi)例閥相(xiang)比(bi)(bi),體積小、重量輕、結構簡(jian)單(dan)、成本(ben)較低(di),但響應速度比(bi)(bi)液壓(ya)系統慢(man)得多,對負載變化也比(bi)(bi)較敏感。
- 使用(yong)功率小(xiao)、發(fa)熱(re)少、噪聲低(di)。
- 不會(hui)發生火災,*。受溫度變(bian)化的(de)影響(xiang)小。
