德國費斯托FESTO標準氣缸

FESTO緊湊性能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）。選型依據-
一、根據管道參數選擇電磁閥的-通徑規格（即DN）、接口方式
1、按照現場管道內徑尺寸或流量要求來確定通徑（DN）尺寸。
2、接口方式，一般>DN50要選擇法蘭接口，≤DN50則可根據用戶需要自由選擇。

二、根據流體參數選擇電磁閥的-材質、溫度組
1、腐蝕性流體-宜選用耐腐蝕電磁閥和全不銹鋼；食用超凈流體-宜選用食品級不銹鋼材質電磁閥。
2、高溫流體-要選擇采用耐高溫的電工材料和密封材料制造的電磁閥，而且要選擇活塞式結構類型的。FESTO緊湊性能電磁閥的工作原理和熱動力式疏水閥相同，它在熱動力式疏水閥的汽室外面增加一層外殼。外殼內室和蒸汽管道相通，利用管道自身蒸汽對疏水閥的主汽室進行保溫。使主汽室的溫度不易降溫，保持汽壓，疏水閥緊緊關閉。當管線產生凝結水，疏水閥外殼降溫，疏水閥開始排水；在過熱蒸汽管線上如果沒有凝結水產生，疏水閥不會開啟，工作質量高。閥體為合金鋼，閥心為硬質合金，該閥zui高允許溫度為550℃，經久耐用，使用壽命長，是高壓、高溫過熱蒸汽疏水閥。
