Uwell VALYRIAN IV Tank Review
The Uwell VALYRIAN IV 8.5mL Refillable Replacement Tank is built for high-performance direct-to-lung vaping, combining a massive e-liquid capacity with UWELL’s latest Advanced V-Coil platform. Designed for powerful vapor production and detailed flavor, the VALYRIAN IV features PRO-FOCS 4.0 Flavor Technology, precise airflow control, convenient top filling, and self-cleaning leak-resistant technology.
With an 8.5mL e-liquid capacity, the VALYRIAN IV is the largest-capacity tank in the VALYRIAN Tank family, allowing longer vaping sessions with fewer refills.

Advanced V-Coils with PRO-FOCS 4.0
The VALYRIAN IV introduces UWELL’s Advanced V-Coils with an optimized mesh structure designed to provide a larger heating area for fast, even vaporization. Combined with organic high-speed wicking cotton and PRO-FOCS 4.0 Flavor Technology, the coil platform is engineered for consistent flavor, dense vapor, and efficient e-liquid delivery.
- 0.18Ω V-Coil: 90–100W – designed for powerful DTL performance and dense vapor production.
- 0.35Ω V-Coil: 50–60W – designed for a lower-wattage DTL experience with detailed flavor.
8.5mL E-Liquid Capacity
The large 8.5mL refillable glass tank provides extended use between refills. This increased capacity is especially useful when vaping at the higher wattages supported by the VALYRIAN V-Coil platform.
Press-to-Open Top Fill System
Refilling is quick and convenient with the VALYRIAN IV’s press-to-open top-fill design. The system provides easy access to the filling port without requiring the tank to be removed from your device.
Precise Adjustable Airflow
A dedicated airflow adjustment ring allows you to fine-tune the draw. Open the airflow for increased vapor production or reduce it for a more concentrated DTL experience.
Self-Cleaning Leak-Resistant Technology
UWELL’s self-cleaning technology is designed to help manage condensation and reduce unwanted e-liquid buildup. Combined with the Advanced V-Coil wicking system, it helps provide a cleaner and more consistent vaping experience.
VALYRIAN II & VALYRIAN III Coil Compatibility
The Uwell VALYRIAN IV Tank supports the latest Advanced V-Coils while maintaining compatibility with VALYRIAN III and VALYRIAN II replacement coils, giving existing VALYRIAN users access to a wider selection of compatible coil options.
Upgraded PEI Drip Tip
The upgraded PEI drip tip provides a durable, heat-resistant mouthpiece suited to the higher power levels associated with DTL and sub-ohm vaping.
