詳細介紹： 　　 GDC-J電磁高真空擋板閥 GDC-J型電磁高真空擋板閥是以電磁力為動力直接帶動閥板動作，使閥門開啟或關閉。適用于真空系統中，用來切斷或導通氣流。適用介質為凈空氣和非腐蝕性氣體。 帶反饋信號。 ■ GDC-] Electro High Vacuum Flapper Valve ■ GDC-JQelectro high vacuum butterfly valve uses electromagnetic force to directly drive valve disc working. thus to make valve opened ro closed. It is applicable for vacuum system to cut off or put through the airflow. When valve is closed. and there is atmospheric pressure above the sealing face and vacuum below the sealing face, here the sealing effect is the best. Applicable medium can be pure air and noncorrosive gases. ■ 主要技術性能 Main Technical Performance ■ ■ ■ 　適用范圍：Applicability 　105～1.3×10-4Pa 　閥門漏率：Valve Leak Rate 　≤1.3×10-4Pa.L/S. 　適用溫度：Applicability 　-30～ 50℃ 　線圍溫升：Coil Temperature Rise 　≤65℃ 　開閉時間：Open-close Time 　≤5S 　電源電壓：Mains Voltage 　220V/50Hz 　安裝方向：Mounting Direction 　任意(可反頂一個大氣壓) ■ 主要零件材料 Materials of Main Parts ■ ■ 閥體、閥板：碳鋼或不銹鋼 密封件：丁腈橡膠、氟橡膠、波紋管(軸封)。 Body, and disc: carbon steel or stainless steel Sealing element: NBR, Viton, bellows(shaft seal) CONSTRUCTION FIGHTS(mm) ■ 外形及連接尺寸(mm) Overall and Connection Dimensions(mm) Model 型號 DN D1 D A B H GDC-J16(b) 16 17.2 30 40 55 193 GDC-J25(b) 25 26.2 40 50 60 203 GDC-J32(b) 32 34.2 55 58 70 237 GDC-J40(b) 40 41.2 55 65 70 244 -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- 相關真空閥產品系列: GDC-J電磁高真空擋板閥 真空管道連接件 GM高真空壓力隔膜閥 DDC-JQ電磁真空帶充氣閥 DYC-JQ電磁真空壓差閥 CC超高真空插板閥 GD高真空擋板閥 GDC-5 電磁高真空擋板閥 CCD電動超高真空插板閥 GDQ氣動高真空擋板閥 GI高真空蝶閥 GID電動高真空蝶閥 GIQ型－氣動高真空蝶閥 GU手動真空球閥 GUD電動真空球閥 GUQ型－氣動高真空(壓力)球閥 GUD系列電動真空球閥
