IdealVac Super-Seal KF-40 Manual Bellows Angle Valve, ISO-KF40 NW40, 304L Stainless Steel
We are proud of our Ideal Vacuum Super-Seal bellows valves as they are manufactured to meet the highest standards. Our bellows valve design includes a hermetically sealed valve stem for leak-free operation, being well suited for high-vacuum applications. These valves operate with a low friction, zero abrasion of the polymer elastomer surface, allowing for repeatable sealing action over thousands of cycles are typical. Save time and money, our premium Super-Seal bellows valves provide high-conductance to maximize the evacuated gas flow rate while minimizing your pump down time.
Our Super-Seal bellows valves are used in applications ranging from semiconductor manufacturing, plasma physics research, to nuclear accelerators. Our inline and angle bellows valves are an ideal choice for many vacuum processes and can be used over the pressure range from 15 PSI positive pressure to 10-9 Torr high-vacuum. They are configured with a variety of end pieces including tubulated ends for welding, CF flanges, KF flanges, and Tube flanges, as well as custom designs.
