力士樂電磁閥技術參數(shù)：
1）根據(jù)介質流向要求及管道連接方式選擇閥門通口及型號；
2）根據(jù)流量和閥門Kv值選定公稱通徑,，也可選同管道內徑,；
3）工作壓差：zui低工作壓差在0.04Mpa以上是可選用間接先導式；zui低工作壓差
接近或小于零的必須選用直動式或分步直接式,。
3,、環(huán)境條件
1）環(huán)境的zui高和zui低溫度應選在允許范圍之內,；
2）環(huán)境中相對濕度高及有水滴雨淋等場合，應選防水電磁閥,；
3）環(huán)境中經(jīng)常有振動,，顛簸和沖擊等場合應選特殊品種，例如船用電磁閥,；
4）在有腐蝕性或爆炸性環(huán)境中的使用應優(yōu)先根據(jù)安全性要求選用耐發(fā)蝕型,；
5）環(huán)境空間若受限制，需選用多功能電磁閥,，因其省去了旁路及三只手動閥且便于在線維修,。
4、電源條件
1）根據(jù)供電電源種類,，分別選用交流和直流電磁閥,。一般來說交流電源取用方
便；
2）電壓規(guī)格用盡量優(yōu)先選用AC220V.DC24V,；
3）電源電壓波動通常交流選用+%10%.-15%,，直流允許±%10左右，如若超差,，須
采取穩(wěn)壓措施,；
4）應根據(jù)電源容量選擇額定電流和消耗功率。須注意交流起動時VA值較高,，在
容量不足時應優(yōu)先選用間接導式電磁閥,。
