GB/T 13932 Check Valve

Check valves are typically used in pipeline systems to prevent media backflow, protecting critical equipment and ensuring proper operation. They are widely applied in piping systems for potable water, water supply and drainage, wastewater treatment, irrigation, HVAC, fire protection, as well as in the chemical and energy industries.

Product Features:

1.  Material: Ductile Iron QT450-10

    The valve body, bonnet, and main disc are all constructed from ductile iron (QT450-10), offering high strength and excellent corrosion resistance.

2.  Epoxy Resin Powder Coating 

    Both the internal and external surfaces of the valve are coated with epoxy resin powder, compliant with the ANSI/AWWA C550 standard, ensuring reliable corrosion protection.

3.  Optimized Structural Design with Low Hydraulic Friction Loss

    The valve features a rational structural design that minimizes hydraulic friction loss.
