德國(guó)寶德BURKERT3320系列資料下載：
創(chuàng)新的 Bürkert 開(kāi)/關(guān)閥門(mén)型號(hào) 3320 是在高要求使用條件下完成斷流任務(wù)的解決方案。帶滾珠絲杠的角座閥電動(dòng)驅(qū)動(dòng)器以超高速 6 mm/s 將轉(zhuǎn)盤(pán)駛?cè)胨璧慕K位置中。同時(shí)，它在一定程度上可無(wú)延時(shí)地反映到過(guò)程信號(hào)上。如有必要，可在斷電時(shí)通過(guò)選裝的蓄能器運(yùn)行至安全位置。電動(dòng)驅(qū)動(dòng)器和斷流閥具有相互匹配且?guī)в心陀帽砻娴姆忾]式設(shè)計(jì)。這可確保達(dá)到快速無(wú)殘留的易清潔性這一衛(wèi)生要求。因其防護(hù)等級(jí) IP65/IP67 和較高的抗波動(dòng)與振動(dòng)特性，電動(dòng)角座閥型號(hào) 3320 可順利地在惡劣的環(huán)境條件中使用。通過(guò)可靠的自行調(diào)整式主軸填料并搭配可更換的頂部套環(huán)，角座閥可達(dá)到長(zhǎng)的使用壽命和高的密封性。現(xiàn)場(chǎng)總線適用的斷流閥型號(hào) 3320 可為運(yùn)營(yíng)商提供諸多有用的功能，以監(jiān)控流程、診斷閥門(mén)和進(jìn)行預(yù)防性維護(hù)，從而帶來(lái)先進(jìn)流程自動(dòng)化的重要優(yōu)勢(shì)。
