Description
Bellows sealed shut-off valve series UV 2x6 are hand-wheeled valves that excel with unique features suitable for a long-time no-maintanance service. Bellows sealing ensures a hermetic tightness to environment and in addition it is added with a safety packing made of graphite. The most advategous feature is low linear forces when opening or closing the valve which does not change during the life-time. Thanks to a yoke design, the valve can be easily insulated and its hand wheel can be operated even at high temperatures of process medium. The hand wheel is non-rising which enables the valves application in tight places. The visible indicator ensures an easy idetification of the valve position.
The valves UV 2x6 Ex comply with requirements of II (1)2G IIB acc. to ČSN-EN 13 463-1.

Application
The valves are especially designed for applications in warm-water and steam circuits in power plants, heating plants, heat exchange stations, heat transferring stations and common heating applications.

Process media
The valves UV 2x6 are suitable for shutting off water, water vapour and other liquids and gases which are compatible with used materials of the valve body and internal materials.
