Reefer Expansion Valves - Container Ship Specific
Reefer expansion valves regulate refrigerant flow into the evaporator of marine refrigerated containers. Thermostatic or electronically controlled designs maintain superheat, cargo temperature stability, and efficient operation under varying ambient and load conditions.
ProShipWorks provides end-to-end support to source and supply Reefer Expansion 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 | Reefer systems are commonly designed to ISO 1496-2 and ISO 5149 or EN 378 requirements. Valve pressure compliance may include the EU Pressure Equipment Directive where applicable. Refrigerant compatibility and OEM reefer-unit specifications must be verified. |
|---|---|
| Class Approval | Individual expansion valves are not normally supplied with universal marine class approval. Acceptance is generally through the approved reefer-container design and OEM specification; container certification may involve ABS, DNV, Lloyd's Register, Bureau Veritas or ClassNK. |
Installation, Maintenance & Safety Information
| Installation Notes | Match the valve to the reefer model, refrigerant, capacity, connection size and flow direction. Keep the circuit clean and dry, braze with nitrogen purge where applicable, correctly position the sensing bulb, leak-test, evacuate and verify superheat. |
|---|---|
| Maintenance Tips | Inspect for refrigerant leakage, corrosion, unstable superheat, restricted strainers and damaged wiring or sensing bulbs. Confirm controller alarms and valve movement. Replace contaminated or sticking valves and renew filter-driers after opening the refrigerant circuit. |
| Safety Notes | Isolate electrical power and recover refrigerant with approved equipment before service. Wear eye and hand protection, ventilate the work area, avoid refrigerant contact, and never heat or open a pressurized refrigeration circuit. |
