Repair Scope

The valve can be replaced separately when it is the diagnosed fault and the electric motor, cylinder, piston group and other compressor components remain serviceable. Different compressor versions can occur on the same model; match the installed unit to the references in Part Number / PN.

Important Before Ordering

Compare the original part number, marking, shape and mounting design before ordering. A model name alone does not confirm the required version.
