Cock Bronze Type U - JIS 16K - F7388
Brass U-Type Cock JIS 16K F7388
Manual U-type cock designed for auxiliary piping systems in marine applications, standardized to JIS, with a nominal pressure rating of 16K and straight-through flow configuration. Construction material is brass, manufactured to F7388 specification.
Operational Use
This valve is intended for local isolation, drainage, venting, or manual control of small-bore lines. The rotary operation enables rapid open/close cycling. It is not recommended for continuous throttling service without monitoring seat wear, as sealing surfaces may degrade under such conditions.
Selection Criteria
- Piping class: JIS 16K
- Valve type: U
- Reference standard: F7388
- Material: brass
- Flow pattern: straight-through
- Verify compatibility with fresh water, service water, or other auxiliary media
Type U vs. Type S
This listing refers to Type U; a corresponding Type S variant also exists. For procurement, request dimensional drawings or datasheets to confirm end connections, handle type, and internal configuration, as F7388 alone may not fully define execution details.
Typical Applications
- Auxiliary fresh water lines
- Drain and vent connections
- Small bypass piping
- Instrument isolation
- Service water lines on vessels
Maintenance
Periodic inspection should include smooth handle rotation, leak-tightness in closed position, internal surface wear, and buildup of scale or solids. For seawater service, confirm material compatibility per project specification.
