Cock Bronze Type S - JIS 16K - F7387
Brass Straight-Through S-Type Valve JIS 16K F7387
Straight-through valve for marine piping systems, manufactured according to JIS F7387 with a nominal pressure class of 16K. Product classification: JIS standard, brass material, straight-through flow configuration, intended for marine installations.
Technical Operation
The S-type valve is used as a manually operated isolation or flow control device in auxiliary shipboard networks. Operation is based on rotational movement of the internal element, enabling rapid transition between open and closed positions.
Selection should not be based solely on DN, but must consider:
- Pressure class JIS 16K
- Brass compatibility with process media
- Operating temperature range
- Leak-tightness requirements in closed position
- Installation location and operator access
Typical Applications
- Auxiliary fresh water lines
- Service water systems on vessels
- Drains and small by-pass lines
- Sampling or venting points, as specified in piping specifications
- Marine piping requiring JIS 16K compliance
Selection Considerations
For seawater, chemical additives, or elevated temperatures, verify material and seal compatibility. For classed or critical service, confirm certification, test standards, and classification society requirements.
Maintenance
Periodic inspection should include smooth handle rotation, leakage in closed position, sealing surface wear, and signs of corrosion or deposits. In systems with scaling risk, more frequent functional testing is recommended to prevent mechanism seizure.
