I. Why It Matters Il pezzo che tutti toccano
A ball valve is the part everyone touches — get it right
A rough action, a leaking stem, or a valve that fails potable-water rules generates complaints faster than any buried fitting. The valve is where your brand gets judged by hand.
A ball valve is the one component in a water system a person physically holds and turns. We are an Italian brass ball valve manufacturer — not a trader repackaging anonymous castings — so every valve traces back to one factory in Bologna, one QC line, and one certificate set.
Low-lead brass — potable-water ready
Cast for potable-water and heating lines. Exact alloy grade and lead-content data sheet: available on request with our certificate set.
Full-bore across 1/2"–2" — full flow
The ball opening matches the pipe bore for minimal pressure drop — one full-bore line covers the whole job, from riser shut-off to meter isolation.
ISO 9001 · 14001 · SKZ · DVGW — tender-ready
Audit- and tender-ready documentation across the Gulf, North Africa and Southern Europe. See our certifications.
II. The Series La gamma
One brass ball valve line, built for every shut-off point
From the main shut-off at the riser to the isolation valve before a meter, the same low-lead line covers every point where flow has to stop cleanly — all available in your branding at container quantities.
| Series | What we manufacture | Notes |
|---|---|---|
| Full-Bore Lever Valve | Standard full-bore ball valve, 1/2"–2", lever handle | Water supply & heating · pressure class Coming soon |
| Butterfly / Wing Handle | Same body with butterfly handle for tight spaces | Handle type; bore matches full-bore line |
| Lockable Valve | Lockable handle for meters & controlled shut-off | Security shut-off · lock detail Coming soon |
| Male / Female Threaded Ends | M/M, M/F and F/F thread configurations | Thread standard — Coming soon |
Series and handle types follow the confirmed WARMHAUS catalogue. Per-series SKU counts, bore DN, thread standards and pressure ratings: Coming soon — confirmed against the full supply table on request.
III. The Alloy La lega è il prodotto
Low-lead brass for potable water and heating lines
The alloy is the product. It decides whether a valve can sit in systems that have to clear potable-water and project requirements — not just hardware-store shelves.
Our ball valves are machined from brass manufactured to low-lead standards suitable for drinking-water and heating applications. As a general industry reference, valve-body brass in this category is typically a low-lead alloy such as CW617N; the specific grade, lead-content figures and machining tolerances we actually use are documented on our material data sheet — shared with distributors and project engineers on request, alongside our ISO 9001, ISO 14001, SKZ and DVGW certificates.
IV. Size Range Tutte le misure
One ball valve line from 1/2" to 2"
A distributor should not have to split a valve order across three suppliers to cover a job. One Italian full-bore line, matched to the pipe you already sell.
Our brass ball valves run the full 1/2", 3/4", 1", 1-1/4", 1-1/2", 2" range — the sizes that carry residential and light-commercial water and heating work.
| Size | Lever Handle | Butterfly Handle | Lockable |
|---|---|---|---|
| 1/2" | |||
| 3/4" | |||
| 1" | |||
| 1-1/4" | |||
| 1-1/2" | |||
| 2" |
The table marks size and handle availability only — handle availability per size is being confirmed against the supply table. Per-size SKU, bore DN, thread standard and pressure class: Coming soon — confirmed on request.
V. Pressure & Handles Specifiche e impugnature
Pressure ratings and handle options for every job
For a project buyer, a ball valve is a spec line before it is a part — the submission has to carry real figures, not assumptions.
As general industry background, brass ball valves in this size class are commonly rated for standard cold- and hot-water working pressures, and full-bore geometry keeps the flow area equal to the pipe. The exact pressure class (PN rating), temperature range and bore diameter for each WARMHAUS size are confirmed on the technical data sheet — issued on request. On the handle side, you choose the type that fits the install:
| Handle Type | Best for | On the valve |
|---|---|---|
| Lever | General shut-off, fast quarter-turn | Red / blue lever, hot/cold coding |
| Butterfly / Wing | Tight spaces, behind panels | Compact wing grip |
| Lockable | Meters, controlled shut-off | Padlock / locking provision |
| Spec item | General industry reference | WARMHAUS documentation |
|---|---|---|
| Pressure class (PN) | Commonly rated for standard cold- & hot-water working pressures | WARMHAUS PN rating per size — Coming soon, on the technical data sheet |
| Working temperature | Cold- and hot-water service typical of this class | Exact range — Coming soon, on request |
| Bore diameter (DN) | Full-bore: flow area equal to the pipe | DN per size — Coming soon, on request |
VI. OEM & Private Label Il tuo marchio
Sell Italian brass ball valves under your own brand
The part that lets you price above generic imports: the Made in Italy origin can be retained on the product — with your name on the body and handle.
For importers ready to build their own plumbing brand, our ball valve line is OEM-ready. We apply your logo and markings to the valve body and handle, produce custom packaging, and offer handle-colour options. Because the same factory makes the matching brass fittings, manifolds and inserts, your customers see one coherent Italian brass system — not a mix of unbranded valves. Small trial orders welcome; OEM MOQ, sampling lead time and packaging minimums: Coming soon — confirmed on request.
FAQ Domande frequenti
Brass ball valves — frequently asked questions
Our brass ball valves are machined from low-lead brass for potable-water and heating lines — the reason they pass drinking-water and tender requirements, not just retail. As general industry reference the alloy is a low-lead type such as CW617N; the exact grade and lead-content data sheet are issued on request with our ISO, SKZ and DVGW documentation.Exact alloy grade & lead-content figures: Coming soon — data sheet on request.
We manufacture brass ball valves across the full 1/2" to 2" range, covering residential and light-commercial water and heating work. That lets you stock one Italian full-bore line instead of splitting orders, and match it dimensionally to the PPR and PEX systems you already sell from the same Bologna factory.Per-size SKU list: Coming soon.
Our standard valves are full-bore, so flow matches the pipe bore for minimal pressure drop. Handles come in lever, butterfly (wing) and lockable types across 1/2"–2" — lever for general shut-off, butterfly for tight spaces, lockable for meters and controlled points.Exact bore (DN) per size: Coming soon — on the data sheet.
