Valyrian 4 Tank
The Uwell Valyrian 4 is a 32mm sub-ohm tank built around the V-Coil platform with PRO-FOCS 4.0 flavour technology. This Uwell Valyrian 4 sub ohm tank handles up to 100W and comes with two V Coils - a 0.18 ohm for 90 to 100W and a 0.35 ohm for 50 to 60W. Both use organic high-speed wicking cotton and mesh heating elements.
The Valyrian 4 tank is also backwards compatible with Valyrian 2 coils and Valyrian 3 coils, so if you've got spares from a previous Valyrian tank they'll fit straight in. This Valyrian vape tank takes high VG shortfill e-liquids (70/30 and above), sits flush on any mod rated for 100W+ thanks to the 32mm diameter, and connects through a standard 510 thread. Available in 5 colours.

V-Coil Platform and Coil Compatibility
The V-Coil platform is the core of the Valyrian 4. These Valyrian 4 coils use a mesh structure with a larger heating area than previous versions, and the organic cotton wicks fast enough to handle chain vaping without dry hits. PRO-FOCS 4.0 (Precise Optimisation of Flavour with Complete Smoothness) matches the power delivery to whichever coil you've got fitted.

All coils are built-in mesh with no separate coil swaps. The U² anti-leak technology uses ultrasonic welding and a U-shaped condensate channel to manage any moisture before it reaches the airflow or fill port.
Airflow and Top-Fill
The bottom airflow ring rotates continuously from restricted DTL through to fully open. There are no click stops - just slide it until the draw feels right. The airflow hits the coil evenly across the full range.
Up top, the press-to-open fill cap works with one hand. Push down on the top cap, add your liquid through the port, and it closes automatically when you let go. The port fits standard bottle nozzles. The glass tube has a silicone protector fitted around it to cushion against drops, and a spare glass tube is included in the box.

Colours
The Valyrian 4 comes in 5 colours: Glossy Black, Neon Rainbow, Pure Gold, Sapphire Blue, and Stainless Steel. All include the silicone glass protector and PEI drip tip.

Why Choose the Valyrian 4 Tank
The Valyrian 4 is the latest in the Valyrian line and the V-Coil platform is a proper step up from the Valyrian 3's coil setup. The backwards compatibility with Valyrian 2 and 3 coils is the practical selling point - you're not locked into one coil range. The 32mm diameter means it needs a full-size mod, but that extra width gives it more capacity and better airflow than a 25mm tank.
If you're after a sub-ohm DTL tank for high VG liquids at 50W to 100W, this is where the Valyrian range has landed. The auto-clean leak-proof tech and organic cotton are genuine improvements over previous versions.
