德國(guó)進(jìn)口burkert 5281先導(dǎo)型伺服控制電磁閥

帶有伺服隔膜的 5281EEx 型先導(dǎo)式閥，根據(jù)其防爆級(jí)別的不同，可被應(yīng)用于易爆環(huán)境中，用于閉塞、計(jì)量及灌注氣態(tài)和液態(tài)介質(zhì)。這樣的壓力需要先到壓力0.2KG，黃銅外殼。burkert產(chǎn)品大致分為六大類：“通用電磁閥系統(tǒng)”“過(guò)程控制閥系統(tǒng)”“氣動(dòng)控制閥系統(tǒng)”“液體分析閥系統(tǒng)”“傳感器/變送器”和 “控制器”，很多產(chǎn)品達(dá)到衛(wèi)生級(jí)標(biāo)準(zhǔn)。

in the process, there will be dead area the process variable deviates from the original set point. So the output of the controller must increase to enough to overcome dead zone, only the corrective action occurs.the main factors influencing dead area. The friction, the moving, valve shaft torsional, amplifier, dead zone. Of various control valve on the friction sensitivity is not the same, such as plug valves for the friction caused by the high seat load is very sensitive, so take note when using. But for some seal type, high seat load is necessary in order to obtain close ranks.
