Balzers EVA025P Vacuum Valve

Balzers EVA 025 P is a compact, DN 25 right-angle vacuum valve designed for reliable isolation in high-vacuum systems, pairing a KF25 flange with an aluminum housing.

The unit uses a pneumatic drive with a bellows-style mechanism, and it seals with FKM (VITON) on both the head and the disc, offering robust chemical resistance and vacuum integrity down to 1×10^-9 mbar.

Its KF25 (NW25) connection makes it compatible with widely used vacuum hardware, enabling straightforward integration into existing systems.

As part of Balzers' BPV valve family, EVA 025 P is positioned as a dependable, high-vacuum isolation element for semiconductor, optical, and related manufacturing environments where precise chamber isolation is essential.
