NORGREN先導(dǎo)閥V61B6DDA-XA020,V61B6DDA-X5020

NORGREN電磁閥如何選型根據(jù)管道參數(shù)選擇NORGREN電磁閥的:通徑規(guī)格(即DN)、接口方式 
按照現(xiàn)場管道內(nèi)徑尺寸或流量要求來確定通徑(DN)尺寸。 
接口方式,一般>DN50要選擇法蘭接口,≤DN50則可根據(jù)用戶需要自由選擇。 
根據(jù)流體參數(shù)選擇NORGREN電磁閥的:材質(zhì)、溫度組 
腐蝕性流體:宜選用耐腐蝕電磁閥和全不銹鋼;食用凈流體:宜選用食品級不銹鋼材質(zhì)電磁閥。 
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(jié)構(gòu)類型的。 
流體狀態(tài):大有氣態(tài),液態(tài)或混合狀態(tài),特別是口徑大于DN25訂貨時一定要區(qū)分開來。 
流體粘度:通常在50cSt以下可任意選擇,若過此值,則要選用高粘度電磁閥。

根據(jù)壓力參數(shù)選擇NORGREN電磁閥的:原理和結(jié)構(gòu)品種 
公稱壓力:這個參數(shù)與其它通用閥門的含義是一樣的,是根據(jù)管道公稱壓力來定。 
工作壓力:如果工作壓力低則必須選用直動或分步直動式原理;zui低工作壓差在0.04Mpa以上時直動式、分步直動式、先導(dǎo)式均可選用。 
電氣選擇:電壓規(guī)格應(yīng)盡量先選用AC220V、DC24較為方便。 
根據(jù)持續(xù)工作時間長短來選擇:常閉、常開、或可持續(xù)通電 
當NORGREN電磁閥需要長時間開啟,并且持續(xù)的時間多余關(guān)閉的時間應(yīng)選用常開型。 
要是開啟的時間短或開和關(guān)的時間不多時,則選常閉型。 
但是有些用于安全保護的工況,如爐、窯火焰監(jiān)測,則不能選常開的,應(yīng)選可通電型。
