Product overview
The CGA540A 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.
Information for your enquiry
Specify the exact model, gas species and required inlet and outlet connections. Confirm the sealing material and service requirements for the requested configuration. A safety-device activation rating must be specified separately before engineering selection.
