Air Compressor Safety Valves - Auxiliary Machinery and Engine Room
Spring-loaded safety valves protect marine air compressors, intercoolers, aftercoolers, and compressed-air receivers from overpressure. They open automatically at a specified set pressure and reseat after pressure returns to a safe level.
ProShipWorks provides end-to-end support to source and supply Air Compressor Safety Valves for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Commonly designed and tested to ISO 4126-1, EN ISO 4126-1, ASME Boiler and Pressure Vessel Code Section VIII, or applicable flag-state and marine statutory requirements. The required standard depends on vessel class, pressure system design, and valve origin. |
|---|---|
| Class Approval | Type approval or product certification may be required from DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK. Approval is manufacturer-, model-, service-, and vessel-specific and must be verified from current certificates. |
Installation, Maintenance & Safety Information
| Installation Notes | Install directly on the protected compressor stage, cooler, or receiver without an isolating valve between the equipment and safety valve. Keep the inlet short and unrestricted, support discharge piping, route discharge safely, and confirm set pressure, capacity, connection, and flow direction. |
|---|---|
| Maintenance Tips | Inspect for corrosion, leakage, fouling, damaged seals, and obstructed discharge piping. Test at class- and maker-specified intervals using approved procedures. Clean and overhaul with specified parts, then bench-test and reseal after any adjustment or repair. |
| Safety Notes | Depressurize, isolate, lock out, and verify zero pressure before removal. Never plug, gag, or isolate an operating safety valve. Do not alter the set pressure without authorization. Vent discharged air away from personnel, oil mist, hot surfaces, and ignition hazards. |
