  • Industrial-Grade Abrasion Defense: Nickel-plated ductile iron discs combat corrosion and particle erosion in high-velocity slurries or chemical-laden fluids.
  • Hydrocarbon-Sealing Expertise: NBR seats maintain integrity in oil/fuel systems, preventing leaks in refineries or fuel transfer pipelines.
  • Space-Smart Installation: Wafer design reduces footprint by 40%, enabling retrofit in cramped industrial layouts without flange modifications.
  • Hammer-Free Reliability: Spring-loaded dual discs shut instantaneously, protecting pumps and pipes from pressure surges in high-flow systems.

Ensure reliable unidirectional flow in demanding environments with the 452 Dual Plate Iron Check Valve, engineered for superior durability and corrosion resistance. Featuring nickel-plated ductile iron discs and a robust NBR seat, this valve excels in high-pressure water, oil, and gas systems, offering leak-free performance and minimal maintenance.

Key Features:

  • Nickel-Plated Discs: Ductile iron discs with nickel plating resist corrosion, abrasion, and wear in aggressive or high-velocity media.
  • NBR Seat Durability: Nitrile seats provide excellent resistance to oils, fuels, and hydrocarbons, ensuring long-term sealing integrity.
  • Wafer-Style Efficiency: Compact, flangeless design installs seamlessly between ANSI B16.1/16.5 flanges, reducing labor and space requirements by 40%.
  • 150# WOG Versatility: Rated for 150 PSI across water, oil, and gas applications, adaptable to mixed-media systems.
  • Dual Plate Precision: Spring-assisted dual discs snap shut instantly to eliminate water hammer and backflow risks.
