    詳情介紹

    product description:

    I. purpose and scope of use of pneumatic vacuum butterfly valve

    GIQ series pneumatic vacuum butterfly valves are used to open or block airflow in a vacuum system of 1.3×10-5 ~ 3×105Pa.

    GIQ series pneumatic vacuum butterfly valve main performance:

    ● leakage rate: ≤1.3× 10-9pa.m3 /S;

    ● applicable pressure range: 1.3× 10-5pa ~ 3×105Pa;

    Working temperature: fluororubber -25℃ ~ +150℃;

    Installation location: arbitrary;

    ● air source pressure: 0.4-0.6mpa;

    ● pressure difference on both sides of the valve plate has nothing to do with valve opening and closing;

    ● life: ≥ 10,000 times.
