  • 316 stainless steel standard trim (chrome carbide, Stellite® & other trim options available)
  • Swing style disc
  • Resilient body/disc optional
  • Mate-lapped ball and seats for 100% sealing area contact, ensuring Class VI shut-off or better
  • Specifications
  • Size: 2"–12" full port (FP)
  • Class: 125–600
  • API 6D
  • API 6A
  • API 594
  • NACE MR0175
  • ISO 15156

Champion Model SD — Spring-Loaded Single Disc

Champion wafer check valves are designed for installation in flanged piping systems in both vertical and horizontal piping. Model SD features a single-disc opening, which allows for unobstructed flow and a stable disc at lower flow velocities. This spring-loaded, lightweight wafer check valve offers superior control, reliability and cost savings in a variety of applications. 

  • Features and Specifications
  • Size: 2"–48"
  • Class: 125–2500
  • Materials: Cast Iron, Carbon Steel, Stainless Steel, Aluminum Bronze, Alloy 20, Monel, Nickel
  • Industry Standards: Complies with ASME, API and MSS industry standards
  • Lightweight deisgn (80-90% less than conventional full-body swing check valves)
  • Increased disc responsiveness alleviates water hammer and resultant damaging effects
  • Extended long-leg spring prevents seat wear caused by scrubbing

Champion Models NZ, NZW — Axial Flow Check Valve

Champion Axial Flow Nozzle Check Valves (Models NZ and NZW) feature a spring-loaded, center-guided, profiled disc and a streamlined axial design that reduces pressure loss through the valve. Among the most efficient anti-slam designs available today, models NZ and NZW are engineered using Champion’s cutting-edge simulation software and leading expertise to provide long-lasting, reliable protection for clean continuous and pulsating liquid and gas flow applications.

  • Features and Specifications
  • Size: 1/2"–54"
  • Class: 150–2500
  • End Connections: Raised Face, RTJ, Weld-End, Socket Weld
  • Industry Standards: ASME, BS, DIN, API 6D
  • Streamlined axial flow path lowers operating costs with minimal pressure drop
  • Anti-slam design for dynamic responsiveness and optimal surge protection
  • Self-aligning conical disc optimizes installation and ensures low maintenance costs
  • Extended long-leg spring prevents seat wear caused by scrubbing
