Frequently Asked Questions

Q: What are the primary materials used in your Ball Check Valves?

Our valves are primarily constructed from Cast Iron (C.I.) or Ductile Iron (D.I.) for the body and bonnet, with sealing elements made from high-quality NBR or EPDM rubber to ensure a tight seal.

Q: Which international standards do these valves comply with?

They are designed and manufactured according to MSS SP-71, BS 5153, and EN 12334, with flange dimensions meeting ASME B16.1/EN 1092 and testing conducted per API 598.

Q: What is the maximum size available for the Ball Check Valve?

Our production line supports a wide range of sizes, with maximum availability up to 24 inches (DN 600) to accommodate large-scale industrial piping.

Q: Can these valves handle corrosive media?

Yes, the combination of Ductile Iron and NBR/EPDM seals provides excellent resistance to a variety of industrial fluids. For highly corrosive chemicals, please contact us for specific material recommendations.

Q: How is the leak-tightness of the valve verified?

Every valve undergoes a rigorous test and inspection process following the API 598 standard to ensure there are no leaks in the body or the seating mechanism.

Q: What is the benefit of using a Ball Check Valve over a traditional Swing Check Valve?

Ball Check Valves typically offer better sealing capabilities, reduced water hammer effects, and a more compact face-to-face dimension, making them ideal for high-pressure environments.
