Bronze globe valves for marine, general industrial, potable water, and low-pressure steam service. Gunmetal (LG2) or bronze (B62) body with renewable brass or bronze seat. Screwed bonnet, inside screw rising stem. Compact and economical for small-bore 1/4 inch to 3 inch applications. BS 5154 / JIS F7301 / ASME B16.15 compliant. LB (Light, PN16) and HB (Heavy, PN25) pressure ratings. BSP or NPT threaded ends. Handwheel operated. Excellent seawater and potable water corrosion resistance.
Technical Specifications

Materials of Construction
| Component | Material |
|---|
| Gunmetal LG2 | BS 1400 LG2 (CuSn5Zn5Pb5) body and disc -- excellent machinability, corrosion resistance in seawater and potable water, good bearing properties |
| Bronze B62 | ASTM B62 C83600 body and disc -- equivalent to LG2, US standard bronze casting alloy for valves and fittings |
| Bronze B61 | ASTM B61 C92200 body -- lead-free bronze option for potable water (low lead content per NSF/ANSI 372) |
| Brass Stem | CZ121 (CuZn39Pb3) inside screw rising stem -- economical, good machinability, suitable for water and low-pressure steam |
Testing & Inspection
| Test | Requirement |
|---|
| Testing | Hydrostatic shell test 1.5 x WP per API 598 / EN 12266-1; Seat leakage test per API 598 / EN 12266-1; Functional test -- full stroke, torque; Material certificates per EN 10204 3.1 |
| Certification | ISO 9001:2015 QMS, EN 10204 3.1 material certificates, hydrostatic and seat test reports |
Applicable Standards
| Standard | Description |
|---|
| Design Standard | BS 5154 Specification for Copper Alloy Globe, Gate and Check Valves, JIS F7301 (marine bronze valves), ASME B16.15 (cast bronze threaded fittings, reference) |
Notes
- Pressure rating (LB / HB / JIS 5K / 10K / 16K), end connection type (threaded BSP/NPT / solder / flanged), and body material (LG2 / B62 / B61) must be specified by the purchaser.
- For potable water service, specify lead-free bronze B61 (ASTM B61, C92200) or gunmetal with lead content compliant to local regulations (e.g., NSF/ANSI 372 in North America).
- For seawater and marine service, specify gunmetal LG2 or bronze B62 with EPDM or PTFE packing; brass stem is not recommended for direct seawater immersion -- upgrade to gunmetal or bronze stem.
- For steam service above 120 deg C, specify graphite packing and confirm bonnet jointing material is suitable for the temperature.
- All valves are manufactured by Supreme Valves India as per our standard specifications.
