4-1 KF系列高真空充气阀（电磁）304
KF series high vacuum charging valve (electromagnetic) 304
Introduction
The valve is driven by electromagnetism. It can inflate in high vacuum pipeline. It has the advantages of small volume, reliable use, good sealing performance and long service life. It is one of the preferred valves for vacuum equipment. The valve is driven by electromagnetic force, which drives the spool to move, thus opening and closing the valve. Its working medium is air and non corrosive gas.
