Globe Valve Cast Steel JIS 20K - F7319

Cast Steel Straight Pattern Globe Valve JIS F7319

The JIS F7319 is a straight pattern globe valve constructed from cast steel, designed for marine piping systems with flanged ends. Product listings typically reference JIS 10K pressure class, though some documentation or URLs may mention 20K. For technical specification and procurement, pressure class must be confirmed via datasheet or supplier quotation.

Test pressures are not to be used as continuous operating pressures. Always verify with pressure-temperature ratings, media temperature, and classification society requirements.

Typical Applications

JIS F7319 valves are used in main and auxiliary shipboard piping where cast steel construction and throttling capability are required:

• Service steam lines
• Fuel or lubricating oil systems
• Compressed air and auxiliary gas lines
• Feed water or service water (subject to piping material compatibility)
• Isolation points upstream or downstream of equipment

Comparison: Cast Steel vs. Cast Iron JIS Valves

Compared to cast iron types (F7307/F7309), SC480 cast steel is selected for installations requiring higher mechanical strength under thermal or pressure loads. Selection depends on pressure, temperature, media, corrosion, flange dimensions, and vessel classification rules.

Selection Considerations

Confirm DN, JIS flange drilling, face-to-face dimensions, pressure class, temperature, trim materials, flow direction, and handwheel accessibility. Standard version is manual; no electric or pneumatic actuator is specified in the product documentation.
