Globe Valve Angle Bronze JIS 5K (Union Bonnet) - F7347

Bronze Angle Globe Valve JIS 5K F7347 Union Bonnet

The JIS F7347 is an angle-type globe valve with Union Bonnet construction, bronze body, and flanged ends to JIS 5K standard. It is used in marine piping systems where a 90° change in flow direction is required, for manual isolation, or for controlled throttling of flow.

Test Pressures

Hydrostatic test values for F7347:

• Body: 1.05 MPa
• Seat: 0.77 MPa

Test values are not to be used as continuous operating pressure. Valve selection must consider medium, temperature, operating pressure, and vessel requirements.

Applications

• fresh water and service water lines
• auxiliary engine room circuits
• oil lines (after compatibility check)
• low-pressure steam, within design limits
• locations requiring angle connection and bonnet access for maintenance

Difference from F7346

The F7346 is a straight-pattern Union Bonnet globe valve. The F7347 is the angle version, selected where piping changes direction by 90°. Flow control function is similar, but installation dimensions, flow direction, and handwheel access differ.

Selection Considerations

Before procurement, confirm DN, JIS 5K flanges, L/H dimensions, packing material, medium, temperature, pressure, and class requirements. Documentation covers manual operation only; actuator options are not specified.
