進(jìn)口氣動(dòng)真空擋板閥
OGD型－氣動(dòng)高真空擋板閥
 OGD-J型為角通型式，OGD-S型為帶預(yù)抽口的三通型式。適用的工作介質(zhì)為空氣及非腐蝕性氣體。氣動(dòng)高真擋板閥在真空系統(tǒng)中作切斷或接通氣流之用。該閥以壓縮空氣為動(dòng)力，通過控制氣動(dòng)元件來改變氣路方向，執(zhí)行氣缸驅(qū)動(dòng)使擋板閥做啟閉運(yùn)動(dòng)。適用的工作介質(zhì)為空氣及非腐蝕性氣性。
注意：氣源壓力(MPa): 0.4～0.6 漏氣率(Pa.L/S): 6.7x10-4介質(zhì)溫度( ℃ ):1.密封材料為橡膠時(shí)-25℃～+80℃ 2.密封材料為氟橡膠時(shí)-30℃～+150℃
氣動(dòng)高真空擋板閥是通過電磁換向閥改變氣路方向，控制執(zhí)行氣缸驅(qū)動(dòng)閥門作啟閉運(yùn)動(dòng)。用于接通或切斷真空管路中的氣流。適用介質(zhì)為純凈空氣和非腐蝕性氣體。
pneumatic high vacuum flapper valve uses solenoid directional valve to change the direction of air passage, and controls the actuating cylinder to drive the valve opened and closed. It is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases.
With signal feedback device.
