Uwell Valyrian IV Tank

Description - Uwell Valyrian IV Tank

The Uwell Valyrian IV Tank is a high-performance sub-ohm vape tank designed for experienced DTL vapers who want powerful flavour, dense vapour production and high-wattage performance. The fourth-generation Valyrian introduces Uwell's new Advanced V-Coil platform alongside PRO-FOCS 4.0 flavour technology, an 8.5ml e-liquid capacity, adjustable airflow and a convenient press-to-open top-fill system.

Designed as the flagship tank in the Uwell Valyrian range, it includes two mesh coil options. The 0.18Ω V-Coil is designed for powerful DTL vaping between 90–100W, while the 0.35Ω V-Coil runs at a lower 50–60W and places more emphasis on a balanced, layered flavour experience.

Advanced V-Coils With PRO-FOCS 4.0

At the centre of the Uwell Valyrian IV Tank is Uwell's latest Advanced V-Coil platform. An optimised mesh structure increases the heating surface area, allowing e-liquid to be vapourised quickly and evenly for dense vapour and a more detailed flavour profile.

The coils also use organic high-speed wicking cotton designed to move e-liquid rapidly towards the heating element. This is particularly important when vaping at higher wattages, helping the coil remain saturated during longer or more frequent draws.

0.18Ω Uwell V-Coil – 90–100W

The 0.18Ω V-Coil is the higher-powered option and is designed specifically for an open DTL inhale. Uwell recommends using it between 90–100W, where it produces warm, dense vapour and large clouds.

0.35Ω Uwell V-Coil – 50–60W

The 0.35Ω V-Coil operates between 50–60W. It uses considerably less power than the 0.18Ω version while still producing a full DTL vape, making it a good choice for vapers who want strong flavour without running close to 100W.

Self-Cleaning Leak-Resistant Design

Uwell has developed a self-cleaning system for the Valyrian IV that redirects condensation back through the atomiser rather than allowing excess liquid to collect around the airflow system.

Combined with the high-speed organic cotton used inside the V-Coils, Uwell states that the design improves leak resistance by up to 30% while helping to reduce the amount of manual cleaning required during normal use.

8.5ml E-Liquid Capacity

With an 8.5ml capacity, the Valyrian IV has the largest capacity in the Valyrian Tank family. The larger reservoir is particularly useful with the 0.18Ω coil, as high-wattage DTL vaping naturally consumes considerably more e-liquid than lower-powered MTL or RDL setups.

For the best experience, this tank is intended for thicker, high-VG e-liquids suited to sub-ohm vaping.

Press-To-Open Top Filling

Refilling the Uwell Valyrian IV is straightforward thanks to its press-to-open top cap. Press the release mechanism to open the tank, add your e-liquid through the filling port and securely close the cap again.

The design avoids having to completely unscrew and remove the top section each time you need to refill.

Adjustable DTL Airflow

A large adjustable airflow system lets you fine-tune how airy the Valyrian IV feels. Opening the airflow increases vapour production and creates a very unrestricted DTL inhale, while closing it slightly provides a warmer and more concentrated draw.

Because both included coils are low-resistance, high-power options, the Valyrian IV is primarily a DTL vape tank rather than an MTL tank.

Heat-Resistant PEI Drip Tip

The upgraded mouthpiece is manufactured from heat-resistant PEI material. This makes it well suited to the higher temperatures produced when running the tank between 50W and 100W, while providing a comfortable wide-bore mouthpiece for DTL vaping.

Protected Glass Tank

A fitted silicone protector surrounds the glass section of the Valyrian IV. It provides additional cushioning against everyday knocks and bumps and helps reduce the chance of accidentally damaging the glass.

Uwell Valyrian IV Coil Compatibility

The Valyrian IV uses the new Uwell Advanced V-Coils, but Uwell has retained compatibility with previous generations of the Valyrian platform.

The tank can also use compatible Valyrian II and Valyrian III coils, giving existing Valyrian users more coil options without immediately replacing their current stock.

Who Is The Uwell Valyrian IV Tank For?

The Valyrian IV is best suited to experienced vapers who enjoy high-power DTL vaping and want substantial vapour production without sacrificing flavour. You'll need a suitably powerful vape setup capable of safely supporting the wattage required by your chosen coil.

The 32mm diameter also means it is better paired with a larger box mod that can accommodate the tank without excessive overhang.

How To Set Up The Uwell Valyrian IV Tank

1. Install your chosen V-Coil securely into the tank.
2. Add a small amount of e-liquid directly to the exposed cotton on a fresh coil.
3. Open the top cap and fill the tank with suitable e-liquid.
4. Close the filling system securely.
5. Allow the coil several minutes to fully saturate.
6. Start below the recommended wattage and gradually increase the power.
7. Adjust the airflow until you find your preferred DTL draw.

Correctly preparing a new coil can significantly reduce the chance of burning the cotton. Read our full guide to priming vape coils if you're installing a new coil for the first time.
