burkert 0263 NBR MS 0-2bar 00026207
0263電磁閥正常關(guān)閉或打開,閥體材質(zhì):黃銅,不銹鋼液體從隔膜的操作機(jī)構(gòu)分離,緊湊的設(shè)計(jì)。在關(guān)閉件周圍形成上低下高的壓差,流體壓力推動(dòng)關(guān)閉件向上移動(dòng),閥門打開;斷電時(shí),彈簧力把先導(dǎo)孔關(guān)閉,入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差,流體壓力推動(dòng)關(guān)閉件向下移動(dòng),關(guān)閉閥門。 斷電時(shí),電磁力消失,彈簧把關(guān)閉件壓在閥座上,閥門關(guān)閉。 特點(diǎn):在真空、負(fù)壓、零壓時(shí)能正常工作,但通徑一般不超過25mm。

The inlet pressure can form a low and high pressure differential around the closing valve through the quick chamber of the bypass hole. The fluid pressure pushes the closing part down and closes the valve. When the power is off, the electromagnetic force disappears and the spring closes the closing piece on the seat and the valve closes. Features: it can work normally when vacuum, negative pressure and zero pressure, but not more than 25mm.
