Frequently Asked Questions
What are the typical applications for a marine globe air valve?
Marine globe air valves are commonly used in shipboard systems for controlling air, gas, and low-pressure steam lines. They are found in engine room compressed air networks, ballast tank vent lines, deck air connections, and other piping systems requiring reliable throttling or shut-off.
What pressure ratings are available?
These valves are typically available in PN16, PN40, and ANSI Class 150 ratings to suit a variety of marine service conditions. Custom pressure ratings may be ordered based on project specifications.
Do you provide classification society certificates?
Yes, we can supply valves with certificates from major classification societies such as ABS, DNV, Lloyd's Register, and Bureau Veritas, upon request. Please specify the required certification when ordering.
What materials are used for the valve seat and disc?
The standard seat ring is made of stainless steel (SS316) for excellent corrosion resistance. For high-temperature or special service, alternative seat materials such as stellite can be supplied.
