Champion Valves Inc. Axial Flow Wafer Check Valves come in two distinct body designs – iron and steel. Our Model NZW valve facilitates a unique flow pattern that reduces slam characteristics and minimizes energy and pressure loss. This economical design offers high- quality performance for liquid, steam, and gas applications.
VALVE FEATURES
Offers efficient drop-in replacement for API 594 check valves in high-turbulence liquid or gas applications.
Face mount assembly allows easy access for maintenance and permits zero fugitive emissions.
Unique patented flow path promotes laminar flow and reduces total pressure loss.
Dual-rated steel body option can be installed between ASME class 150 and 300 flanges.
Internally mounted compression-style spring boasts a longer life than torsion-style springs.
