DNV Approved Valves – Class Certified Valves for Marine & Offshore Systems
- DNV approved valves are marine valves certified to comply with DNV classification requirements for shipboard and offshore applications.
- These valves are designed, tested, and approved to operate safely under harsh marine conditions.
- DNV approval confirms valve quality, material compliance, pressure rating, and operational performance.
- Using DNV approved valves supports vessel inspections, compliance, and reliable system operation at sea.
Why DNV Approval is Important
- Ensures valves meet strict marine safety and class requirements.
- Required for many critical shipboard systems and offshore installations.
- Supports successful acceptance during classification surveys and port inspections.
- Reduces risk of system failure, leakage incidents, and non-compliance penalties.
Marine Applications for DNV Approved Valves
- Main engine and auxiliary engine systems.
- Fuel oil and lubrication oil pipelines.
- Cooling water and seawater circulation systems.
- Ballast and bilge pipelines.
- Firefighting and emergency safety systems.
- Hydraulic and pneumatic shipboard systems.
- Offshore utility and process pipelines.
Types of DNV Approved Valves Available
- Gate Valves for pipeline isolation and full flow service.
- Globe Valves for throttling and controlled flow regulation.
- Check Valves for reverse flow prevention and equipment protection.
- Ball Valves for quick shut-off with tight sealing.
- Butterfly Valves (wafer, lug, high performance, triple offset) for large pipelines.
- Pressure Control & Safety Relief Valves for overpressure protection and safe regulation.
Marine-Grade Materials and Construction
- Manufactured using stainless steel, bronze, carbon steel, duplex and alloy steel materials.
