The Marine Air Vent Head is a critical component designed for use in oil and water tanks on various ships and offshore drilling platforms. Manufactured and inspected according to CB 20037-2012 or CB/T 3594-1944 standards, this air vent head ensures optimal venting and pressure regulation for tank systems, contributing to the safety and functionality of marine vessels.

Available in nominal diameters ranging from DN50 to DN450, the air vent head is made with flanges compliant to CB/T 4196-2011 and GB/T 2501-2010 standards. This flexibility makes it suitable for a wide range of marine applications.

The air vent head comes in various structural types, including cap type, gooseneck type, combined sounding type, cylindrical float type, and ball float type. Additionally, depending on the flange standards and tank usage (oil or water), there are 14 different model variations, such as 14 A, AS~G, and GS. These models are available in cast iron or cast steel, offering durability and reliability in harsh marine environments.
