Double Doors C594 Disc One Way Valve DN300 12INCH

 

Dual Disc Check Valve features two semi-circular discs pivoted on a central shaft with torsion springs for quick, low-pressure opening in forward flow, automatically closing to prevent backflow and protect piping systems from reverse pressure. Ideal for water, wastewater, and industrial applications, with a retainerless body for leak-free performance.

    Product Advantage

    Wafer style installs between ANSI class 125/150 companion flanges (or comparable). 

    Dual door / dual disc design: two independent plates, typically spring-loaded or torsion-hinged for quick closing response.

    Body material: ductile iron (often ASTM A536 grade 65-45-12). 

    Disc material: Aluminum bronze (C954) for corrosion resistance and durability. 

    Soft-seat / elastomeric seat (EPDM, NBR, etc) for tight sealing and minimal leakage. 

    Compact face-to-face length (wafer style) for easier installation in tight pipe-runs. 

    Low pressure drop design (due to the dual disc arrangement and streamlined body). 

    Suitable for both horizontal and vertical installations (manufacturer data should be confirmed). 

    Typical service: water, chilled water, HVAC, non-slurry industrial fluids; check manufacturer spec for temperature and medium limitations.
