Cla-Val 100PM-4 Magazine Sprinkler Valve

The Cla-Val 100PM-4 is an automatic control valve designed for dry and wet type magazine sprinkling systems on marine vessels. It is specified for fire protection circuits where hydraulic control of sprinkler flow is required, rather than simple manual line isolation. Product documentation references compliance with MIL-F1183.

Technical Classification

  • Type: Magazine Sprinkler Valve
  • Series Codes: 100PM-4 / 100PM-4B
  • System Compatibility: dry and wet magazine sprinkling
  • Typical Service: seawater-based sprinkling / fire protection
  • Connection for 100PM-4: Union MIL-F1183
  • Quick catalog reference: 1" for magazine and cargo sprinkling, dry/wet type
  • Relevant drawing: 803-6397408 for sizes 1 1/2"–8"

EP and MS Suffixes

The Cla-Val catalog specifies that the EP suffix indicates ethylene propylene elastomers, while the MS suffix denotes a version with limit switch. Suffix selection should be based on fire system specifications, especially for seawater, AFFF, or position monitoring requirements.

Operational Role

The 100PM-4 is integrated into magazine or cargo hold sprinkler systems. Its operation depends on the system’s hydraulic logic, pilot lines, local/remote actuation, and activation requirements. It should not be replaced with a standard on/off valve without verifying the control diagram.

Selection Considerations

  • Confirm 100PM-4 or 100PM-4B variant
  • Requirement for MIL-F1183 or alternative connection
  • Fire main pressure and available sprinkler flow
  • Elastomer compatibility with seawater or AFFF
  • Need for limit switch for monitoring
  • Access for testing, flushing, and maintenance

Maintenance

Inspection should include diaphragm, pilot tubing, seat, internal ports, seawater deposits, and functional testing from designated control stations. After testing or activation, flushing is required per system procedure.
