GU Series (Manual ball valve)

GU-50(KF)

In vacuum industry, ball valves are durable and usually work to achieve perfect shutoff. A ball valve is a vacuum valve with a ball in the central part of the valve, and the ball controls the flow through it. The ball has a hole, through the middle so that when the hole is in line with both ends of the valve, flow will occur. Ball valves have rugged structure ,which provides high reliability in “dirty” vacuum application. They are widely used in the process equipment,food processing lines,CVD equipment and many other industrial applications. Vacuum ball valves offer straight-through, unimpeded flow with minimal space requirements, and they would be applied for relatively high pressure, high temperature environment.

Vacuum ball valves are used in a wide range of applications, including Semiconductor processing, vacuum engineering, freeze-drying and fusion research,plastic molding process and vacuum tubes,medical applications and others. A vacuum ball valve with pneumatic actuators is used to pick and drop objects in ro
