Adjustment valve for the air conditioning compressorN280

Adjustment valve for the air conditioning compressor -N280-

The adjustment valve is integrated in the compressor. It is activated by theAir conditioning command and indicator unit / Climatronic -E87- or by theClimatronic control unit -J255-. The adjustment valve influences the pressure in the low pressure section, thus regulating the temperature in the evaporator.

Note

The Adjustment valve for the air conditioning compressor -N280- is an integral part of the compressor and cannot be replaced separately.
