Frequently Asked Questions

Q: What is the difference between SS 304 and SS 316 ball valves?

SS 304 is ideal for general corrosion resistance, while SS 316 contains molybdenum, providing superior resistance to chlorides and marine environments.

Q: What does 1000 WOG mean for this valve?

WOG stands for Water, Oil, and Gas. A rating of 1000 WOG means the valve is certified to handle these mediums up to a working pressure of 1,000 PSI.

Q: Are these ball valves compatible with ANSI standards?

Yes, our valves feature NPT threaded ends that are fully compliant with the ANSI B1.20.1 standard for secure and universal fitting.

Q: Can these valves handle extreme temperature fluctuations?

Absolutely. Our valves are designed to operate reliably in temperatures ranging from -40 to 400 Degrees F.

Q: What is a "blowout-proof stem" and why is it important?

A blowout-proof stem prevents the stem from being ejected from the valve body under high pressure, significantly increasing operator safety.

Q: How are these valves tested before shipping?

Unlike batch testing, we perform 100% individual pressure testing on every single valve to ensure absolute leak-proof performance.
