Vacuum valves & Valves - Pfeiffer Vacuum

Vacuum Valves

Angle valves are employed in a wide range of applications. They are characterized by their high level of tightness and their robustness. The flange sizes range from DN 5 ISO-KF to DN 160 ISO-K. Aluminum and stainless steel are available as materials.
Inline valves are used wherever installation without a 90° angle is necessary.
Butterfly valves close by pivoting a disk perpendicular to the passageway.

Pressure relief valves

In addition to the shut-off function, specially designed valves are also employed for gas dosing in a vacuum process.
In addition to the shut-off function, specially designed valves are also employed for gas dosing in a vacuum process.
Ball valves are very rugged and, depending on their size, can be used both in medium vacuum environments and at high overpressures. The limiting factor is usually small-flange outlet connections, as the industry standard restricts their use to 1500 hPa over pressure and less.
  • Space saving, compact design
  • Smooth actuation for low particle generation
  • In-situ serviceability through removable body cover
  • Wide selection of gate O-ring compounds

The vacuum valve in different versions
Pfeiffer Vacuum vacuum valves are used in wide-ranging solutions in industrial applications and research areas. In order to meet these requirements as fully as possible, the vacuum valves are divided according to size, type of flange and drive, and according to the pressure range used. Therefore, there are manually operated vacuum valves with ISO-KF flanges or CF flanges as well as electro-pneumatically operated vacuum valves that are also offered with ISO-K flanges. In contrast, the electromagnetically operated vacuum valves are only constructed with ISO-KF flanges due to their operating principle. There are special vacuum valves in all-metal designs for use in the UHV area and vacuum valves, so-called gas metering valves, for controlling pressure as well as for the measured gas supply in vacuum systems. Depending on demand, many of these vacuum valves are available in aluminium and stainless steel.

The vacuum valve and its areas of application
The Pfeiffer Vacuum vacuum valves are just as individual as your requirements. So, for example, corner valves are frequently used in freeze-drying, partial drying, or gas separation. In comparison, bellows-sealed gate valves are generally used wherever large nominal sizes are needed (> DN 100), such as in coating systems.

The excellent tightness of our vacuum valves is essential, especially for applications under high vacuum or ultra-high vacuum. Also decisive for the use of vacuum valves are factors such as long service life, low maintenance requirements and short opening and closing times. Wherever space is crucial for the selection of the corresponding vacuum valves, mini angle or inline valves are used. electro-pneumatic or electromagnetic vacuum valves are excellently suited for systems requiring an automated process flow.

User-friendliness of the vacuum valve
To enable you to manage your work easily, easy operation of the vacuum valves plays a crucial role in addition to the technical qualities. Depending on which valve type is best suited for your requirements, you can rely on saved labor through integrated position sensors and on a service life up to 10 million cycles. In addition, the Pfeiffer Vacuum valves are designed to provide optimal handling. Ergonomically shaped handles are, of course, just as integral to the design features as the low amount of force needed to open or close the valves. However numerous the areas of application for the vacuum valve may be, the selection of different version is just as large - the decisive factor is the right choice for you. We ensure that you use exactly the vacuum valve that is best suited for your needs.
