Questions buyers ask
What pressure, flow and temperature is it rated for?
These valves are rated for 3,360 PSI. The listing does not specify flow coefficient (Cv) or temperature range; ask the seller for the flow rating and operating temperature limits if your application requires verification of those parameters. CGA350 valves typically handle moderate flow rates appropriate for cylinder service, but the actual Cv varies by manufacturer and model.
What gases is it compatible with, and has it been oxygen cleaned?
The listing does not indicate whether these valves have been oxygen cleaned; if you need them for oxygen service, confirm with the seller whether they meet CIP (Cleaned for Intended Product) requirements or if additional cleaning will be necessary. The brass body and nylon seat are generally suitable for inert and fuel gases, but verify material compatibility with your specific gas.
What materials are the wetted parts?
The body is forged brass, the seat is nylon, and the valve uses a brass diaphragm in packless construction. The listing mentions optimized O-ring design and references a metal-to-metal seal below the bonnet threads, but does not specify the elastomer material used for those seals; ask the seller for the O-ring compound if chemical compatibility is critical for your application.
What should I inspect before putting it into service?
Since these are new 2020 manufacture, verify that all outlet threads and sealing surfaces are undamaged and free of debris, confirm the pressure relief device operates freely, and check that handwheels turn smoothly through their full range. Before cylinder installation, pressure-test the valves to your facility's acceptance criteria and verify the PRD burst disc rating matches your service pressure requirements, as unitized PRDs may have different settings depending on configuration.
