GIQ型－气动高真空蝶阀 ■ GIQ型气动高真空蝶阀是通过电磁换向阀改变气路方向，控制执行气缸驱动蝶阀作启闭运动。用于接通或切断真空管路中的气流。适用介质为净空气和非腐蚀性气体。可选配反馈信号装置及电气阀门定位器。 ■ GIQ Pneumatic High Vacuum Butterfly Valve ■ GIQ pneumatic high vacuum butterfly valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the butterfly valve opened and closed. It is used to put through or cut off the airflow in vacuum pileline. Applicable medium can be pure air and noncorrosive gases. They may be fitted with signal feedback device and electropneumatic valve positioner. ■ 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：Applicable Temperature 　-25～ 80℃(丁腈橡胶) 　-30～ 150℃(氟橡胶) 　气源压力：Mains Voltage 　0.4～0.6MPa 　安装方向：Mounting Direction 　任意 ■ 主要零件材料 Materials of Main Parts ■ ■ 阀体、阀盖、阀杆：碳钢或不锈钢 密封件：丁腈橡胶、氟橡胶。 Body, bonnet and stem: carbon steel or stainless steel Sealing element: NBR, Viton CONSTRUCTION FIGHTS(mm) ■ 外形及连接尺寸(mm) Overall and Connection Dimensions(mm) Model 型号 DN D Do D1 B H B1 L n-φc GID-40 40 85 70 44 22 162 90 104 4-φ7 GID-50 50 110 90 55 22 175 90 104 4-φ7 GID-65 65 125 105 70 26 198 102 140 4-φ9 GID-80 80 145 125 85 30 208 102 140 4-φ9 GID-100 100 170 145 105 30 220 102 140 4-φ12 GID-150 150 220 195 156 35 272 115 164 8-φ12 GID-200 200 275 250 208 40 330 205 190 8-φ12 GID-250 250 330 300 258 45 335 205 190 8-φ14 GID-300 300 380 350 308 55 426 152 247 8-φ14 GID-400 400 500 465 410 60 520 180 308 8-φ18 GID-500 500 600 565 510 80 643 220 378 12-φ18 GID-600 600 710 670 610 100 760 270 524 12-φ21 GID-800 800 920 815 815 130 962 320 648 20-φ21 GID-1200 1200 1440 1280 1280 150 1360 385 1480 36-φ19
