Hose Valve Bronze JIS 10K - Nakajima - F7334
Brass Fire Hydrant Valve JIS 10K Nakajima F7334
Manual fire hydrant valve for marine water networks, type F7334, with brass body, flanged connection, straight-through flow design, and Nakajima hose outlet. Product title specifies JIS 10K class, but the “Nominal Pressure” field lists 5K; flange pressure class must be verified prior to order or replacement.
Typical Application
Used in ship fire main systems, fire hose stations, decks, engine rooms, and auxiliary fire water networks. Straight-through design is selected when the hose outlet is aligned with the pipeline axis.
Technical Selection Points
- Type: JIS F7334
- Body material: Brass
- Network connection: Flanged
- Hose outlet: Nakajima
- Configuration: Straight-through
- Operation: Manual
- Medium: Fire water
Before installation, verify DN, JIS flange drilling, actual pressure class, Nakajima type, flange gasket, and class society requirements.
Materials and Maintenance
Brass is specified for marine applications due to improved corrosion resistance in wet environments compared to cast iron. For seawater networks, check galvanic compatibility, seat condition, stem packing, and salt deposits at the Nakajima coupling.
Difference from 5K Version
The 10K version must only be used when flange, design pressure, and drilling conform to JIS 10K. Do not substitute for 5K without dimensional and system specification verification.
