Here are the details on Zoloto Gun Metal / Bronze Valves (many times “Gun Metal” is used interchangeably with bronze / high-copper alloys) from the publicly available info. If you tell me which exact model (e.g. globe, gate, check, ball etc.), I can narrow further. But below is a general idea + specific examples.
🔍 What is “Gun Metal” in Valves
-
Gun Metal is a traditional name for a copper-tin alloy (bronze) often with some zinc. It’s good for corrosion resistance, especially in water / steam / non-aggressive media.
-
Materials used in Zoloto “bronze” / “gun metal” valves are often IS 318 (Bronze – LTB2) or similar bronze/bronze-type alloys.
⚙️ General Features of Zoloto Gun Metal / Bronze Valves
From Zoloto’s catalog and product listings for bronze / gun-metal valves, these are common characteristics:
| Feature | Detail |
|---|---|
| Standards / End Connections | Usually screwed female ends per IS 554 / BS 21 / ISO 7 when screwed; or flanged ends for flanged versions. |
| Valve Types | Ball valves, globe valves, check (non-return) valves, safety relief valves, etc. |
| Seating / Seals | Usually PTFE (for soft seal) in many models; sometimes metal seats when required. |
| Maximum Working Temperature | ~ 220-225 °C for many bronze/gun metal / steam-capable valves; lower (e.g. ~90-100 °C) for some water / non-steam versions. |
| Hydrostatic / Test Pressures | Varies by model, but shell test often ~25 kg/cm²g (≈ 350 psig) for many bronze ball-valves. Seat test ~16 kg/cm²g (≈ 225 psig) in such cases. |
| Media Compatibility | Water, oil, steam, air, gases in many cases. |
