The difference between manual/pneumatic/electric ultra-high vacuum plug-in valve
It is driven by a handwheel with a screw, and the connecting rod mechanism is pushed (pulled) by a transmission rod to drive the valve plate to move axially, achieving the opening or closing of the valve, thereby achieving the purpose of connecting or cutting off the airflow in the ultra-high vacuum system. Reasonable in structural design, beautiful in appearance, and with advantages such as smooth operation, small volume, large flow channel, reliable use, good sealing performance, and long service life, it can be widely used in ultra-high vacuum equipment
