Globe Valve Angle Cast Iron JIS 10K - F7308

JIS 10K F7308 Cast Iron Angle Globe Valve

The JIS F7308 is an angle pattern globe valve constructed from cast iron, featuring flanged ends to JIS 10K standard. Designed for marine and industrial piping systems where a 90° change in flow direction is required, it enables manual throttling or isolation. The angle configuration eliminates the need for separate pipe elbows, but pressure drop across the valve must be considered during line sizing.

Technical Specifications

• Design standard: JIS F 7308-1996
• Test standard: JIS F 7400-1996
• Pattern: Angle flow
• Connection: Flanged
• Pressure class: JIS 10K
• Body: FC200 cast iron
• Bonnet: FC200

Test Pressures

Hydrostatic shell test: 2.1 MPa up to DN200, 1.5 MPa for DN250 and above. Seat test: 1.54 MPa up to DN200, 1.1 MPa for DN250 and above.

Applications

• Auxiliary engine room piping
• Fresh water and service water lines
• Cooling water circuits with JIS 10K flanges
• Piping systems requiring 90° flow direction change
• Flow control points upstream/downstream of equipment

For seawater service, assess corrosion risk, internal protection, trim material, and galvanic compatibility with the piping system.

F7308 vs F7307

F7307 is a straight pattern JIS 10K cast iron globe valve. F7308 is the angle pattern equivalent. Selection depends on piping geometry, flow direction, installation space, and handwheel accessibility.

Selection Considerations

Confirm DN, JIS 10K flange drilling, face-to-face dimensions, pressure, temperature, media, disc/seat material, and classification society requirements. Standard configuration is manual operation; no actuator is specified on this page.
