\u88fd\u54c1\u8aac\u660e<\/h2>\n

A pneumatically actuated vacuum ball valve in 316 stainless steel, with an ISO-K flange that clamps straight into a standard ISO-K line \u2014 no adapter. The air actuator opens and closes it in a fraction of the time a hand-operated valve takes, which is the point: on a vacuum line, the valve is usually the slowest thing in the sequence.<\/p>\n

Available in ISO80 (DN80, 3\u2033) and ISO100 (DN100, 4\u2033).<\/p>\n

Where This Valve Belongs \u2014 and Where It Does Not<\/h2>\n

A ball valve is not the right valve everywhere in a vacuum system, and we would rather tell you that up front than have it arrive and be wrong.<\/p>\n

Position in the system<\/th>\nWhat it does there<\/th>\nIs a ball valve right for it?<\/th>\n<\/tr>\n<\/thead>\n
Fore-line \/ roughing line isolation<\/strong><\/td>\nBetween the pump and the chamber, on the roughing or backing line.<\/td>\nYes \u2014 this is what a vacuum ball valve is for.<\/strong><\/td>\n<\/tr>\n
Vacuum pump isolation<\/strong><\/td>\nShutting a pump out of the line so it can be serviced or swapped without venting the whole system.<\/td>\nYes.<\/strong><\/td>\n<\/tr>\n

High-vacuum chamber main valve<\/td>\nThe main gate between a chamber and a turbo pump, holding high or ultra-high vacuum.<\/td>\n\u305d\u3046\u3060\u3002<\/strong> That is the job of an angle valve or a gate valve, not a ball valve. We will tell you so rather than sell you the wrong thing.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

If you are isolating a pump, a fore-line, or a gauge, a ball valve is the straightforward, fast, full-bore answer. If you are gating a chamber at high vacuum, you want an angle valve or a gate valve \u2014 a different tool for a different job.<\/p>\n
