Quantity
Vacuum conditions are used in industrial applications for pick and place systems, and research laboratories. In these processes, vacuum ball valves are often used to keep the 'negative' vacuum pressure in the chamber or pipe and as a channel for the vacuum generators or pumps. A vacuum rated ball valve should possess several characteristics for operation in a vacuum environment. The most important characteristics are the ability to have very good sealing properties in the shut-off position, quick response time, and the ability to operate at pressure differences between the sides of the valve. In some vacuum applications, the valve should operate at sub-zero conditions.
High vacuum ball valves offer straight-through, unimpeded flow with a minimal valve body footprint. Because of their unique design, ball valves are less sensitive than other vacuum valves to particulate contamination and, therefore, are especially useful in ‘dirty’ vacuum applications. For example, ball valves are almost always used to isolate scrubbers and traps downstream of the rough pumping system
