JIS F 7333 A is a Japanese Industrial Standard (JIS) specification for marine bronze gate valves, primarily used in shipboard piping systems for fluid isolation and control.
Key Features of JIS F 7333 A:
Material & Design:
Constructed from bronze (e.g., JIS BC6) for excellent corrosion resistance in seawater and marine environments.
Features a gate valve design with a wedge or parallel disc mechanism for full flow or complete shut-off.
Applications:
Commonly installed in fuel oil, ballast water, and cooling systems on ships.
Suitable for high-pressure industrial pipelines requiring reliable isolation.
Performance Standards:
Pressure Rating: Typically rated for 1.0 MPa (10 bar) or higher, depending on class.
Temperature Range: Operates between -20°C to +150°C (short-term peaks up to +200°C).
Leakage Class: Complies with JIS B 2005 for tight sealing.
Testing & Compliance:
Requires hydrostatic pressure tests (1.5x working pressure) and material inspections.
Aligns with ISO 10434 and ASME B16.34 for international interoperability.
Variants:
Differs from JIS F 7333 B (globe valves) by its gate valve structure and on/off functionality.
For detailed dimensions or certifications, consult manufacturer specifications.
Note: The standard may include sub-classes (e.g., Type A-1, A-2) for specific pressure/temperature grades.
