Frequently Asked Questions

Q: What is the difference between SS304 and SS316 for ball valves?

SS304 is ideal for general corrosion resistance, while SS316 contains molybdenum, providing superior resistance to chlorides and marine environments, making it better for highly corrosive chemicals.

Q: Can these valves be used for high-temperature steam?

Yes, our valves are rated for saturated steam up to 150 psi and can withstand temperatures up to 180°C.

Q: What does "Investment Cast Body" mean for quality?

Investment casting ensures high dimensional accuracy, a smoother surface finish, and stronger structural integrity compared to sand casting, reducing the risk of internal flaws.

Q: Are these valves suitable for oil and gas applications?

Absolutely. They are specifically recommended for water, oil, and gas, with a max working pressure of 25 Bar to ensure safe operation.

Q: Why is "Silicone-Free" manufacturing important?

Silicone-free manufacturing prevents contamination in painting or high-precision coating processes where silicone residues could cause surface defects.

Q: What sizes are available for these threaded ball valves?

We offer a comprehensive range of sizes starting from 1/4 inch up to 4 inches to fit various piping configurations.
