What are the uses of shipboard relief valves?

In maritime operations, the safe and efficient transport of steam, air, and other fluids is essential. Shipboard overpressure prevention systems such as steam pressure relief valves and air compressor relief valves maintain a safe and efficient shipboard environment by preventing damage to equipment or health hazards to the crew.

In particular, shipboard air compressor relief valves prevent the pressure within air-driven systems from exceeding system limits. This ensures proper and safe functionality for:

  • Control systems, instrumentation, and general-purpose pneumatic tools
  • Air receiver tanks
  • Firefighting equipment
  • Ballast control systems
  • Air start systems for internal combustion engines
  • Pneumatic steering systems

The Danco D48CUU Shipboard Air Compressor Relief Valve is built to ensure reliable performance for these systems and other shipboard systems.
