意大利ATOS比例閥特點: - 可(ke)實現(xian)壓(ya)力、速度的無極(ji)調節,避免了常通(tong)的開關式氣閥換向時的沖擊現(xian)象。
- 能(neng)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(yuan)件大大減少。
- 與液壓比(bi)例閥相比(bi),體(ti)積小、重(zhong)量輕、結(jie)構簡單、成本較低,但響應(ying)速度比(bi)液壓系統慢(man)得(de)多,對負載(zai)變化也比(bi)較敏感。
- 使用功率小、發熱(re)少、噪(zao)聲低。
- 不會(hui)發生(sheng)火災,*。受溫度變化的影響(xiang)小。
