Uwell VALYRIAN IV Replacement Tank
Uwell VALYRIAN IV Replacement Tank
The Uwell VALYRIAN IV is the fourth generation of Uwell's flagship sub-ohm tank, built in stainless steel and high-borosilicate glass with an 8.5mL capacity and a 32mm diameter. It runs on the V-Coil platform — 0.18Ω and 0.35Ω mesh heads are included — and is fully backward-compatible with Valyrian II and Valyrian III coils, so existing coil stock carries straight over. A press-to-open top-fill cap refills it one-handed without unscrewing anything, bottom airflow control tunes the draw from restricted to wide open, and Pro-FOCS 4.0 plus Uwell's self-cleaning leak-proof design keeps condensation out of the airflow path. It finishes with a heat-resistant 810 PEI drip tip and a threaded 510 connection.

FAQ
Q: Will my Valyrian II or Valyrian III coils work in this tank?
A: Yes. The Valyrian IV uses the same V-Coil platform, and Uwell confirms full compatibility with Valyrian II and Valyrian III coils. Any V-Coil you already own will screw straight in.
Q: What wattage should I run each coil at?
A: The 0.18Ω V-Coil is rated for 90–100W and the 0.35Ω for 55–65W. Start at the low end of the range, take a few short priming puffs, then work up — jumping straight to the ceiling on a dry coil is the fastest way to burn the cotton.
Q: Will this fit my mod?
A: It uses a standard threaded 510 connection, so it fits almost any sub-ohm box mod. At 32mm diameter it will overhang the top plate of narrower mods — check that your device is at least 30mm wide if you want a flush fit.
Q: What e-liquid should I use with it?
A: High-VG freebase e-liquid, 70VG/30PG or higher, in low nicotine strengths — typically 0–6mg. Do not use high-strength nicotine salts in a sub-ohm tank at these wattages.
Q: How do I fill it?
A: Press the top cap to slide open the fill port, insert your bottle nozzle, fill to just below the top of the chimney, then press the cap closed. Let a freshly installed coil sit for 5–10 minutes before the first draw.
Q: Is the glass replaceable, and is a spare included?
A: Yes. The kit ships with a spare bubble glass tube, an O-ring pack and a silicone glass protector. Replacement glass for the Valyrian series is widely available if you need more later.
