Hose Valve Cast Iron Angle JIS 10K - Nakajima - F7333
Cast Iron Angle Fire Valve JIS 10K Nakajima F7333
Manual angle fire valve for marine water networks, type F7333, with cast iron body, flanged connection, JIS 10K pressure class, angle flow configuration, and Nakajima hose outlet. Product specification includes JIS standardization, flanged end, cast iron material, nominal pressure 10K, and angle pattern design.
Technical Application
The angle pattern is used at fire hose take-off points where the outlet must change direction by 90° relative to the pipeline. Typical installation locations include ship fire mains, decks, engine rooms, bulkheads, and hose stations with limited available space.
Selection Criteria
- Type: JIS F7333
- Body material: Cast Iron
- Pressure class: JIS 10K
- Network connection: Flanged
- Hose outlet: Nakajima
- Pattern: Angle flow
- Operation: Manual
- Service media: Fire water
Prior to procurement, confirm DN, JIS 10K flange drilling, Nakajima coupling type, flange gasket, fire main operating pressure, and class society requirements.
Difference from Straight F7333
The straight version is used when the hose outlet is aligned with the pipeline axis. The angle F7333 is selected when a change of direction is required at the take-off point, eliminating the need for an additional angle fitting.
Maintenance
In marine environments, cast iron requires inspection of coating, bolts, flange, and local corrosion. Periodic checks should include seat tightness, stem or packing leakage, free handwheel rotation, and Nakajima coupling cleanliness.
