Features & Benefits
Superior Corrosion Resistance
NiAlBr provides exceptional resistance to seawater, chlorides, and acidic environments, outperforming standard bronze and stainless steel in marine applications.
Full Bore Design
Full bore construction ensures unrestricted flow, minimal pressure drop, and allows for pigging operations in pipeline applications.
Low Maintenance
Self-lubricating PTFE seats and anti-galling properties of NiAlBr ensure smooth operation with minimal maintenance requirements.
Complete Traceability
Full material traceability with Mill Test Certificates (MTCs) and compliance documentation as per international standards.
