GD-J型高真空擋板閥--產(chǎn)品介紹：

GD-J型高真空擋板閥(又稱角閥)是用于真空系統(tǒng)中用來切斷或接通氣流之用。傳動(dòng)部件采用螺桿傳動(dòng)升降閥板，動(dòng)作輕巧、工作可靠。GD-J為角通型式,GD-S為帶預(yù)抽口的三通型式。適用的介質(zhì)為空氣及非腐蝕性氣體。傳動(dòng)部件采用螺紋結(jié)構(gòu)。高真空擋板閥動(dòng)作輕巧、工作可靠，高真空擋板閥適用溫度范圍: －30℃－＋150℃GD-J系列高真空擋板閥是用于真空系統(tǒng)中用來切斷或接通氣流之用。

GD-J型高真空擋板閥適用的工作介質(zhì)為空氣、非腐蝕性及不含顆粒灰塵的氣體。

GD high vacuum flapper valve is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases. According to its shaft seal structure, high vacuum flapper valve is classified into GD-J rubber shaft seal type and GD-J(b)bellows shaft seal type. According to its put-through type, it is classified into GD-J angle type and GD-S three-way type with prepumping.
