美國ASCO防爆電磁閥在選型時的注意事項一、適用性
美國ASCO防爆電磁閥的選型依據電磁閥選型首先應該依次遵循安全性，可靠性，適用性，經濟性四大原則，其次是根據六個方面的現場工況（即管道參數、流體參數、壓力參數、電氣參數、動作方式、特殊要求進行選擇）。
美國ASCO防爆電磁閥管路中的流體必須和選用的電磁閥系列型號中標定的介質*。流體的溫度必須小于選用電磁閥的標定溫度。電磁閥允許液體粘度一般在20CST以下，大于20CST應注明。工作壓差，管路zui高壓差在小于0.04MPa時應選用寧波艾爾派克公司如ZS,2W,ZQDF,ZCM系列等直動式和分步直動式；zui低工作壓差大于0.04MPa時可選用先導式（壓差式）電磁閥；zui高工作壓差應小于電磁閥的zui大標定壓力；一般電磁閥都是單向工作，因此要注意是否有反壓差，如有安裝止回閥。流體清潔度不高時應在電磁閥前安裝過濾器，一般電磁閥對介質要求清潔度要好。注意流量孔徑和接管口徑；電磁閥一般只有開關兩位控制；條件允許請安裝旁路管，便于維修；有水錘現象時要定制電磁閥的開閉時間調節。注意環境溫度對電磁閥的影響電源電流和消耗功率應根據輸出容量選取，電源電壓一般允許±10%左右，必須注意交流起動時VA值較高。
