Frequently Asked Questions

Q: What are the primary materials used in the DIN Swing Check Valve?

The body is made of high-strength Ductile Iron, the plug from Carbon Steel, and the seat from Brass for superior sealing. The hinge pin is crafted from S.S. 13Cr to prevent corrosion.

Q: Which international standards does this valve comply with?

Our valves strictly follow BS 5153/EN 12334 for design, BS 4504/DIN 2533 for flange dimensions, and API 598/EN 12266 for testing and inspection.

Q: What is the maximum available size for this check valve?

The DIN Swing Check Valve is available in a wide range of sizes, supporting installations up to 36 inches.

Q: Can these valves be used in high-pressure environments?

Yes, thanks to the Ductile Iron body and Carbon Steel internal components, these valves are engineered to handle significant pressure while maintaining a secure seal.

Q: How does the brass seat benefit the system?

The brass seat provides an excellent balance of hardness and sealing capability, reducing the risk of leaks and extending the interval between maintenance cycles.

Q: What is the function of the NBR gasket in this valve?

The NBR (Nitrile Butadiene Rubber) gasket ensures a flexible yet tight seal, providing resistance to oils and water to prevent external leakage.
