Technical Datasheet -- Bronze Globe Valves for Marine, Water, and General Industrial Service
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.
| Parameter | Specification |
|---|---|
| Product Type | Bronze Globe Valves |
| Category | Globe Valves |
| Size Range | 1/4" to 3" (DN8 to DN80) |
| Pressure Rating | LB (Light: PN16 / 200 psi WOG) / HB (Heavy: PN25 / 300 psi WOG) -- JIS 5K / 10K / 16K on request |
| End Connections | Threaded BSP / NPT (1/4" to 2"), Solder end (1/4" to 1-1/2", copper tube), Flanged RF per JIS B2220 (1/2" to 3", on request) |
| Body Material | Gunmetal LG2 (BS 1400 LG2, CuSn5Zn5Pb5) / Bronze B62 (ASTM B62, C83600, CuSn5Zn5Pb5) / Bronze B61 (ASTM B61, C92200, CuSn5Zn2Pb2) |
| Disc Material | Bronze LG2 or B62 with ground seating surface / Brass CZ122 (CuZn39Pb3, on request for lower cost) |
| Seat Material | Renewable bronze or gunmetal seat ring (screwed-in) / integral body seat (economical) |
| Stem Material | Brass CZ121 (CuZn39Pb3) -- inside screw, rising stem, guided in bonnet bushing |
| Bonnet Type | Screwed bonnet with PTFE or hemp and paste jointing (standard) / bolted bonnet (on request for high pressure) |

The Bronze Globe Valve -- Threaded BS 5154 LB / HB is designed, manufactured, and tested in accordance with applicable API / ASME / BS / ISO international standards. Compliance documentation and Material Test Certificates (EN 10204 3.1) are provided with every order.
Standard construction is carbon steel, stainless steel (CF8 / CF8M), and special alloy grades. Alternative and upgraded grades -- Duplex, Super Duplex, Inconel, Monel, Hastelloy, and NACE MR0175 trims for sour service -- are available on request.
It is offered in a range of sizes as per the technical specification with standard ANSI / ASME pressure classes (PN ratings on request). End connections include flanged (RF / RTJ), butt-weld, socket-weld, and screwed ends as per specification.
Yes. Supreme Valves India is an established exporter of industrial valves to Saudi Arabia (KSA), the UAE, Qatar, Kuwait, Oman, Bahrain, and across the Gulf. We provide sea-worthy export packing, EN 10204 3.1 / 3.2 certification, certificate of origin, and support for SABER / SASO conformity on KSA shipments.
Every valve undergoes hydrostatic shell and seat testing per API 598 / ISO 5208. Documentation includes EN 10204 3.1 MTC (3.2 on request), NDT reports, and fire-safe (API 607) or NACE MR0175 certification where applicable. Third-party inspection by TÜV, SGS, Bureau Veritas, or Lloyd's Register can be arranged.
Order quantities are flexible -- from single units for stocked items to bulk volumes for project requirements. Lead time depends on size, material, and quantity; please contact our team with your specification for a firm delivery schedule and quotation.
