Features & Benefits
Superior Corrosion Resistance
NiAlBr provides exceptional resistance to seawater, chlorides, and acidic environments, outperforming stainless steel in marine applications.
Quarter-Turn Operation
90° rotation from fully open to fully closed provides quick and easy operation with minimal operator effort.
Compact & Lightweight
Wafer design requires minimal installation space and reduces overall system weight compared to other valve types.
Complete Traceability
Full material traceability with Mill Test Certificates (MTCs) and compliance documentation as per international standards.
Test Pressure Requirements
| Test Type | Pressure (Class 150) | Standard |
