防爆電動(dòng)球閥介紹：

防爆電動(dòng)球閥是一種轉(zhuǎn)角為90°的旋轉(zhuǎn)類球閥，密封性能優(yōu)良，流通能力大，流阻系數(shù)小，結(jié)構(gòu)簡(jiǎn)單、維修方便、使用壽命長(zhǎng)，閥體通道和連接管徑相等并成一直徑，介質(zhì)幾乎可以毫無(wú)損失的流過。輸入4-20mA信號(hào)及220VAC/380VAC電源即可控制運(yùn)轉(zhuǎn)。國(guó)標(biāo)壓力等級(jí):1.0-16Mpa、美標(biāo)150Lb300Lb600Lb900Lb材質(zhì):鑄鋼、碳鋼WCB不銹鋼SS304SS316SS316L。產(chǎn)品通常用于密封要求嚴(yán)格的場(chǎng)合，除控制氣體、液體、蒸汽介質(zhì)外，還適宜控制污水和含有纖維性雜質(zhì)的介質(zhì)，電動(dòng)球閥旋轉(zhuǎn)90°即可全關(guān)全開，與相同規(guī)格的閘閥、截止閥比較、球閥體積小、重量輕，便于管道安裝。廣泛用于石油、化工、冶金、輕工、造紙、電站、制冷等工作領(lǐng)域。
