Produktbeschreibung<\/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

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
