Globe Valve Angle Bronze JIS 16K (Union Bonnet) - F7349

Bronze Angle Globe Valve JIS 16K F7349 Union Bonnet

The JIS F7349 is an angle globe valve with Union Bonnet construction, flanged ends to JIS 16K, designed for small-bore marine piping systems where a 90° change in flow direction and manual throttling are required. The product is referenced as Bronze 16K Angle Valve, Union Bonnet Type per JIS F 7349-1996.

These are test pressures, not continuous operating pressures. Selection must consider temperature, medium, pressure-temperature rating, duty cycles, and class society requirements.

Applications

• Fresh and service water lines
• Oil lines (after compatibility check)
• Low/medium pressure steam (within material limits)
• Piping requiring 90° flow change
• Locations needing bonnet access for maintenance

Comparison: F7349 vs F7348

F7348 is a straight pattern Union Bonnet globe valve (JIS 16K). F7349 is the angle pattern variant, used where piping geometry requires a 90° flow turn without a separate elbow.

Selection Considerations

Before procurement, verify DN, JIS 16K flange compatibility, L/H dimensions, medium, pressure, temperature, flow direction, packing type, and handwheel access. Manual operation is standard; no actuator is specified in the reference.
