XF-12A Gas Cylinder Valve
1 / 3
The XF-12A is a cylinder valve for carbon dioxide and sulfur hexafluoride service. It combines a pressure-sealed construction with a flat-face sealing interface.
The cylinder inlet and equipment outlet are specified separately for connection matching. Check both interfaces and the sealing arrangement against the mating components when selecting this exact model.
Key advantages
- Specified gas service — A cylinder-valve configuration for carbon dioxide and sulfur hexafluoride service.
- Flat-face mating interface — Match the flat sealing face as well as the connection designation when selecting mating equipment.
- Connection matching — Check the cylinder-side and equipment-side connections independently for this model.
