For a well-known shipping company, we’ve delivered a large‑dimension overboard valve from Barthel Armaturen ⚓ whose specification is exceptional, even within the segment of major shipbuilding components. The DN500 valve, with a leg length of 525 mm, an installation height of approximately 1,300 mm, and a weight of around 500 kg, clearly illustrates the significance of this hull‑mounted valve 📏. The valve is designed for continuous operation in seawater 🌊 — a medium that places substantial long‑term demands on both material selection and manufacturing quality. Consequently, such a unit will be delivered with a classification certificate, independently confirming its tightness and functional performance. Its installation position on the ship’s shell plating below the waterline imposes additional requirements ⚙️, as both installation and removal are only possible in dry dock. Any later intervention is practically excluded due to the inaccessible location on the external hull.
