Product overview
The CGA-350 is a cylinder valve for hydrogen service. It combines a pressure-sealed construction with a 70° cone seat. This version has a left-hand outlet connection. Check its thread designation and sealing interface against the mating equipment; models in the same family are not automatically interchangeable.
Key advantages
Hydrogen
A cylinder-valve configuration for hydrogen 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.
