意大利ATOS比例閥特點: - 可實現壓力、速(su)度的無極調節,避(bi)免了常通的開關式氣閥換向(xiang)時的沖擊(ji)現象(xiang)。
- 能實現(xian)遠程控制和程序(xu)控制。
- 與(yu)斷續控制相比(bi),系統簡化,元件(jian)大大減(jian)少(shao)。
- 與液壓比(bi)例閥(fa)相(xiang)比(bi),體積小(xiao)、重量(liang)輕(qing)、結構簡單(dan)、成本(ben)較低,但(dan)響應速度比(bi)液壓系統慢得多(duo),對負載變化也比(bi)較敏感。
- 使用功率小、發熱少、噪聲低(di)。
- 不會發生(sheng)火(huo)災,*。受溫度變化的影響小。
