GIQ型－氣動高真空蝶閥 ■ GIQ型氣動高真空蝶閥是通過電磁換向閥改變氣路方向，控制執(zhí)行氣缸驅動蝶閥作啟閉運動。用于接通或切斷真空管路中的氣流。適用介質為凈空氣和非腐蝕性氣體。可選配反饋信號裝置及電氣閥門定位器。 ■ 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：Applicable Temperature 　-25～ 80℃(丁腈橡膠) 　-30～ 150℃(氟橡膠) 　氣源壓力：Mains Voltage 　0.4～0.6MPa 　安裝方向：Mounting Direction 　任意 ■ 主要零件材料 Materials of Main Parts ■ ■ 閥體、閥蓋、閥桿：碳鋼或不銹鋼 密封件：丁腈橡膠、氟橡膠。 Body, bonnet and stem: carbon steel or stainless steel Sealing element: NBR, Viton CONSTRUCTION FIGHTS(mm) ■ 外形及連接尺寸(mm) Overall and Connection Dimensions(mm) Model 型號 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
