進口氣動真空蝶閥|負壓真空蝶閥|氣動的真空蝶閥

進口氣動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。適用介質為純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。

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.

進口氣動真空蝶閥有它自己的明顯特征：

    ● 漏率：≤1.3×10-9Pa.M3/S;

    ● 適用壓力范圍：1.3×10-5Pa～3×105Pa;

    ● 工作溫度：氟橡膠-25℃～+150℃；

    ● 安裝位置：任意；

    ● 閥板兩側壓力差對閥門開、關無關；

    ● 壽命：≥10000次。
