Vacuum Manual Angle Valve with ISO-K Flange


A stable, economical and versatile valve assembly, which is suitable for applications in high-vacuum and ultra-high-vacuum systems that require cleanliness and corrosion resistance.
By using high-quality welded bellows, full opening can be achieved, thus realizing extremely large flow conductance.
The number of opening and closing cycles in the laboratory can reach up to 1 million times.

Valve body material: SUS304
Bellows 

material: SUS321
Sealing method: Fluororubber


Pneumatic opening pressure: 1.2 bar


Leakage rate: 1.x10⁻⁹ mbar L/s


Vacuum degree: 1x10⁻⁹ Torr

There are multiple forms of flange interfaces and opening methods for customers to choose from.

Both 2D and 3D models can be provided. Non-standard customization is accepted. If you have any requirements, you can consult our sales engineers.
