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.
