氣動(dòng)截止閥產(chǎn)品概述
J641H氣動(dòng)截止閥由法蘭鑄鋼截止閥、直行程氣缸、電磁閥、限位開關(guān)和氣源附件等組成的自控閥門系統(tǒng)，氣動(dòng)截止閥是一種依靠壓縮空氣驅(qū)動(dòng)可實(shí)現(xiàn)遠(yuǎn)距離、大規(guī)模集中控制的自控閥門。通常用在需要頻繁開閉且要求開閉時(shí)間較快的場(chǎng)合，或者是安裝不方便人工控制的特殊位置空間，特別適合工藝現(xiàn)場(chǎng)沒(méi)有電源等驅(qū)動(dòng)源需集中閥門的開閉的工藝管道或者裝置中。
氣動(dòng)截止閥產(chǎn)品特點(diǎn)
1、采用加大型特殊硬化工藝處理的閥桿以適應(yīng)氣動(dòng)截止閥一般開閉頻繁，速度快的工藝特點(diǎn)，防止閥桿彎曲變形失效而減短閥門壽命；
2、可選擇單作用氣缸 或者雙作用氣缸以使用不同的工藝要求；
3、選用不同的閥門主體材料可使用于空氣、水、蒸汽、油及硝酸、醋酸等對(duì)種介質(zhì)流體；
4、選用防爆電磁閥可用于需要防爆的工作環(huán)境；
5、可根據(jù)客戶要求選用不同的零部件用于特殊工藝環(huán)境
