技術參數：

1）根據介(jie)質流向(xiang)要求及管道連接方(fang)式選擇(ze)閥門(men)通口及型號；

2）根據流量(liang)和(he)閥門Kv值選定公稱(cheng)通徑，也可選同管道內(nei)徑；

3）工作(zuo)壓(ya)差(cha)：低(di)工作(zuo)壓(ya)差(cha)在0.04Mpa以上是可選用間(jian)接(jie)先導式；低(di)工作(zuo)壓(ya)差(cha)接(jie)近或小于零(ling)的必須(xu)選用直動式或分步直接(jie)式。

德國REXROTH電磁(ci)閥環境條件:

1）環(huan)境的高(gao)低溫(wen)溫(wen)度應選(xuan)在允許范圍之(zhi)內；

2）環境中相對(dui)濕(shi)度高及有水(shui)滴雨淋(lin)等場合，應選防水(shui)電磁(ci)閥；

3）環境(jing)中經常有振動，顛簸和沖擊等場合(he)應(ying)選特殊品種，例如船(chuan)用電磁(ci)閥(fa)；

4）在有腐(fu)蝕(shi)性或爆炸性環境(jing)中(zhong)的使用應優先根(gen)據安全(quan)性要求選用耐發蝕(shi)型；

5）環(huan)境(jing)空間若受限制，需選用(yong)多功能電磁閥，因其(qi)省去了(le)旁(pang)路及三只手動閥且(qie)便于在(zai)線維(wei)修。
