Understanding MIL-V-22549 Compliance

Dante Valve focuses on meeting the highest military standards for materials and construction. We make certain our valves can stand up to the high stakes of maritime operations and the rigorous demands of naval vessel operating conditions.

MIL-V-22549 sets the standard for naval shipboard pressure relief valves for air service. It specifies valve design, materials of construction for body and spring housing, pressure-temperature ratings, and other standards. Compliance with these specific requirements for shipboard air compressor valves ensures:

  • Designs tailored to specific performance and reliability criteria to provide dependable performance
  • Long-term durability from robust materials and manufacturing processes to withstand harsh environments
  • Broad compatibility and interoperability with military ship systems, streamlining installation and maintenance
  • Adherence to specific quality control procedures and standards during design, production, and testing
  • Prioritization of safety for personnel, equipment, and the ship as a whole
  • High performance in extreme conditions such as high temperatures, vibrations, and corrosive elements

Our focus on ensuring compliance with MIL-V-22549 standards ensures the Danco D48DUU relief valve can get the job done in any situation.
