Sperre HV-series compressors supply starting air on a large number of merchant ships. The HV2/240 and its sister models are simple and durable, but their valves and rings work hard.
Typical wear items
- LP and HP suction and delivery valves, or their valve plates and springs
- Piston rings for both stages
- Cylinder head gaskets and valve cover O-rings
- Cooler O-rings and drain valve parts
- Unloader valve components
Valve designs have changed across production years, so match the compressor serial number when ordering. Keeping one complete set of LP and HP valves on board avoids a long wait when charging time starts to rise.
