介質特性

1）質(zhi)氣，液態(tai)或混合(he)狀態(tai)分別選用(yong)不同品種(zhong)的電(dian)磁(ci)閥；

2）介質溫度不同(tong)規(gui)格(ge)產品(pin)，否則線(xian)圈會燒掉，密封件老化(hua)，嚴重影響壽命(ming)命(ming)；

3）介質粘度，通常在50cSt以下。若超過此值，通徑(jing)大(da)于15mm時，用多功能電磁(ci)閥；通徑(jing)小于15mm時，用高粘度電磁(ci)閥。

4）介質清潔度不(bu)高時都應在電磁閥前配裝反沖過濾閥，壓力低時，可(ke)選用直動膜(mo)片式電磁閥；

5）介質若是定向(xiang)流通，且不允許倒流，需用雙向(xiang)流通；

6）介(jie)質(zhi)溫度應選在電磁閥允許范圍之內。
