详细介绍： 　　 GDC-J电磁高真空挡板阀 GDC-J型电磁高真空挡板阀是以电磁力为动力直接带动阀板动作，使阀门开启或关闭。适用于真空系统中，用来切断或导通气流。适用介质为净空气和非腐蚀性气体。 带反馈信号。 ■ 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. ■ 主要技术性能 Main Technical Performance ■ ■ ■ 　适用范围：Applicability 　105～1.3×10-4Pa 　阀门漏率：Valve Leak Rate 　≤1.3×10-4Pa.L/S. 　适用温度：Applicability 　-30～ 50℃ 　线围温升：Coil Temperature Rise 　≤65℃ 　开闭时间：Open-close Time 　≤5S 　电源电压：Mains Voltage 　220V/50Hz 　安装方向：Mounting Direction 　任意(可反顶一个大气压) ■ 主要零件材料 Materials of Main Parts ■ ■ 阀体、阀板：碳钢或不锈钢 密封件：丁腈橡胶、氟橡胶、波纹管(轴封)。 Body, and disc: carbon steel or stainless steel Sealing element: NBR, Viton, bellows(shaft seal) CONSTRUCTION FIGHTS(mm) ■ 外形及连接尺寸(mm) Overall and Connection Dimensions(mm) Model 型号 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 -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- 相关真空阀产品系列: GDC-J电磁高真空挡板阀 真空管道连接件 GM高真空压力隔膜阀 DDC-JQ电磁真空带充气阀 DYC-JQ电磁真空压差阀 CC超高真空插板阀 GD高真空挡板阀 GDC-5 电磁高真空挡板阀 CCD电动超高真空插板阀 GDQ气动高真空挡板阀 GI高真空蝶阀 GID电动高真空蝶阀 GIQ型－气动高真空蝶阀 GU手动真空球阀 GUD电动真空球阀 GUQ型－气动高真空(压力)球阀 GUD系列电动真空球阀
