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.
