CGA-540J Gas Cylinder Valve
1 / 3
The CGA-540J is a cylinder valve for oxygen service. It combines a pressure-sealed construction with a 70° cone seat.
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
- Oxygen — A cylinder-valve configuration for oxygen service.
- Cone-seat connection — The defined cone seat helps identify the required mating sealing geometry.
- Connection matching — Check the cylinder-side and equipment-side connections independently for this model.
