F-4E1 Gas Cylinder Valve
1 / 3
The F-4E1 is a cylinder valve for acetylene 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
- Acetylene — A cylinder-valve configuration for acetylene 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.
