Frequently Asked Questions

Find quick answers to some of the most common questions

Does the Dragon 2Y Needle Valve provide bubble‑tight shutoff?

Yes. The metal‑to‑metal needle and seat design delivers tight shutoff suitable for high‑pressure instrumentation and process isolation.

Is the 2Y Needle Valve fire‑safe?

Yes. The forged body, metal seat, and graphite packing make the 2Y suitable for fire‑safe service in high‑temperature and hydrocarbon environments.

What end connections are offered?

The 2Y is available with NPT, SW, BW, and tube‑fitting ends, covering instrumentation, sampling, and high‑pressure piping applications.

How does the OS&Y design improve reliability?

The outside screw and yoke keep threads out of the process media, reducing corrosion, improving stem alignment, and extending valve life in severe service.
