If your project specifies DNV-certified marine valves, ensure the supplied valves possess type approval rather than merely conforming to standards. When procuring marine valves for shipbuilding or offshore applications requiring DNV certification, provide valve type, size, pressure rating, and application details to facilitate swift and accurate technical review.
We manufacture marine valves for shipbuilding and offshore applications. Selected valve models are certified with DNV (Det Norske Veritas) Type Approval, ensuring compliance with DNV rules and international marine standards.Please feel free to inquire about prices or ask any questions.
