Vape accessories
by Storz & Bickel
The SOLID VALVE Set is a complete balloon-filling system designed by Storz and Bickel for use with all Volcano desktop vaporizers. Unlike the Easy Valve — which uses pre-made, disposable balloon units — the Solid Valve lets you cut your own balloons to any length you like, giving you full control over bag size, vapour density, and running costs. It is the hands-on option for people who want to customise their sessions rather than accept a one-size-fits-all setup.
Every Solid Valve Set ships with everything you need to start filling balloons straight out of the box — no extra purchases required on day one. Here is the full breakdown of what arrives in the package:
| Item | Quantity | Notes |
|---|---|---|
| Solid Valve with Balloon | 1 | Pre-assembled, ready to use |
| Balloon Tube | 1 (3 m roll) | Cut to your preferred length |
| Mouthpiece | 1 | Clips onto the balloon end |
| Filling Chamber for Herbs | 1 | Holds approximately 0.5 g of dried herb |
| Normal Screen Set | 1 | Replacement screens for the valve |
| Liquid Pad | 1 | Approx. 24 mm diameter x 5 mm — for concentrates and oils |
| Cleaning Brush | 1 | For routine maintenance of the filling chamber |
The 3-metre balloon tube is the star here. Most people cut bags between 30 cm and 60 cm long, so one roll gives you roughly five to ten replacement balloons depending on your preference. When a bag gets cloudy or starts tasting stale, you snip a fresh one and clip it on — takes about 30 seconds.
The Solid Valve and Easy Valve both fit every Volcano model, but they work differently in practice. The Solid Valve is the original system — it has more parts, requires you to assemble your own balloons, and needs regular cleaning. The Easy Valve uses pre-attached bags that you simply replace when they get tired. Here is a direct comparison:
| Feature | Solid Valve Set | Easy Valve Starter Set |
|---|---|---|
| Balloon size | Custom — cut any length from the 3 m roll | Fixed size (standard or XL) |
| Herb chamber capacity | Approx. 0.5 g | Approx. 0.75 g |
| Assembly required | Yes — attach balloon, fit mouthpiece | Minimal — bags come pre-assembled |
| Cleaning | More involved — valve disassembles into several parts | Simpler — fewer parts to maintain |
| Running cost per balloon | Lower — tube is cheap per metre | Higher — replacement bags cost more per unit |
| Concentrate use | Yes, with included Liquid Pad | Yes, with Liquid Pad (sold separately on some sets) |
Our honest take: the Easy Valve is more convenient, no question. But if you use your Volcano daily, the Solid Valve saves you money over time because replacement balloon tube is significantly cheaper per bag than buying pre-made Easy Valve balloons. It is the best Volcano valve system for daily users who do not mind spending 60 seconds on assembly.
The Volcano has been on the market since 2000 and Storz and Bickel have not changed the Solid Valve design much — because it works. The filling chamber is machined aluminium with a brushed finish that feels genuinely solid in the hand. There is no plastic creaking, no wobble. The valve mechanism itself clicks shut with a satisfying snap that seals the balloon airtight, keeping vapour fresh for several minutes after filling.
The 0.5 g filling chamber is slightly smaller than the Easy Valve's 0.75 g capacity. For solo sessions, that is actually a benefit — you use less material per bag and get denser vapour from a smaller load. If you are filling bags for a group, you will just refill the chamber more often. Not a dealbreaker, but worth knowing before you buy.
One thing we have noticed over the years: the screens in the Solid Valve clog faster if you grind too fine. A medium grind gives the best airflow. Go too coarse and you lose extraction efficiency; go too fine and you will be swapping screens every few days. The included Normal Screen Set gives you spares, but pick up an extra set if you are a heavy user — you will want them within the first month.
Keeping the Solid Valve clean is the trade-off for its lower running costs. Residue builds up inside the valve housing and on the screens after every few sessions. Here is a straightforward cleaning routine that takes about 10 minutes:
Skip the cleaning for a couple of weeks and you will taste it — stale, slightly burnt flavour that no amount of fresh herb can mask. Stay on top of it and the Solid Valve delivers clean-tasting vapour session after session. That is the honest deal with this system: it rewards maintenance and punishes neglect.
| Spec | Value |
|---|---|
| Manufacturer | Storz and Bickel (Germany) |
| SKU | VS0033 |
| Compatible devices | Volcano Classic, Volcano Digit, Volcano Hybrid |
| Filling chamber capacity | Approx. 0.5 g dried herb |
| Balloon tube length | 3 metres (cut to size) |
| Liquid Pad dimensions | Approx. 24 mm diameter x 5 mm height |
| Material use | Dried herbs and concentrates (via Liquid Pad) |
| Cleaning | Isopropyl alcohol soak, included brush |
Complete your Volcano setup with the Solid Valve Balloon Tube replacement roll — one roll keeps you stocked for months. If your screens are wearing thin, the Solid Valve Normal Screen Set is the part you will reach for most often. And if you are using concentrates regularly, grab an extra Liquid Pad set so you always have a clean one ready while the other soaks.
Yes. The Solid Valve Set is compatible with every Volcano model — Classic, Digit, and Hybrid. The filling chamber attachment is the same across all three units.
With daily use, most people swap the balloon every one to two weeks. You will know it is time when the bag turns cloudy, feels sticky, or starts giving off an unpleasant taste even after a fresh fill.
Yes. The included Liquid Pad sits inside the filling chamber and absorbs concentrates or oils, allowing them to vaporise evenly. Apply a small amount — a little goes a long way on the 24 mm pad.
It has more parts to disassemble, so yes, cleaning takes a bit longer. Budget about 10 minutes every week or two. Soak everything in isopropyl alcohol, scrub with the included brush, rinse, and air dry. Not difficult — just more hands-on than the Easy Valve.
Start with 40 cm. That gives a good balance between vapour density and volume. Shorter bags (25-30 cm) fill faster and deliver more concentrated hits. Longer bags (50-60 cm) suit group sessions but the vapour cools and thins out more.
Approximately 0.5 g of dried herb. That is slightly less than the Easy Valve's 0.75 g chamber, but more than enough for a solo session. A medium grind gives the best airflow and extraction.
Yes. Replacement balloon tube costs less per bag than pre-made Easy Valve balloons. Over months of daily use, the savings add up noticeably. The trade-off is the extra minute of assembly each time you replace a bag.
