Delphi Air Conditioning Compressor Control Valve CPX021 – V5, Yellow 41 Psig

This Delphi air conditioning compressor control valve is listed as Part No. CPX021 and is described as an OEX Air Conditioning Compressor Control Valve for Delphi units. It is a single piece component, supplied each, with a stated one year warranty and a very light weight of 0.02 kg.

The key application detail provided is for Delphi V5 compressors, with the features note stating Yellow - 41 PSIG. There is also a note that references Purple Valve - 41psig, so the control valve identification and pressure setting should be checked carefully against the compressor fitted to the vehicle before ordering.

This is a compressor control valve rather than a complete compressor, so the important match points are the compressor make, the compressor family, and the pressure specification. The supplied fitment information points to a number of Holden and HSV applications, but the exact vehicle match should still be confirmed against the compressor details and part number CPX021.

For buyers replacing a failed A/C control valve, matching the valve type and pressure rating matters because the compressor relies on the correct control valve to regulate operation. Using the wrong valve can lead to incorrect compressor control, so the listed Delphi V5 and 41 PSIG details are the first checks to make.

Fitment guidance provided

• Holden applications are listed, including Calais, Caprice, Commodore, Monaro and Statesman variants.
• HSV applications are listed, including GTS, Manta and Senator variants.
• Some application groupings include model-year references such as 1997, 1998, 1999, 2000, 2001 and 2002.
• Fitment information is tied to the compressor/control valve application and should be checked against the fitted Delphi compressor and part number CPX021.
• Because the fitment preview is application-based rather than a full vehicle build record, the compressor itself should be matched before purchase.

Application and Buying Notes

When replacing a compressor control valve, the safest first check is the compressor make and model family. This valve is identified for Delphi units and specifically for Delphi V5 compressors, with a Yellow - 41 PSIG feature note, so the compressor fitted to the vehicle needs to align with those details.

Part number matching is just as important as the vehicle name. CPX021 is the clearest identifier here, and the notes also mention Purple Valve - 41psig. If the compressor label, valve colour, or pressure setting on the unit does not line up, the part should be verified again before ordering.

The supplied application data includes Holden and HSV model families, but those names alone are not enough to confirm a match. The practical check is whether the fitted compressor is the Delphi V5 type associated with this valve and whether the pressure specification matches the compressor requirement.

If you are comparing this against a removed part, use the part number CPX021, the Delphi brand reference, and the 41 PSIG pressure note as the main comparison points. Those details are more reliable than a general vehicle model name when you are selecting an air conditioning compressor control valve.

Because A/C control valves are application-specific, do not assume all Delphi compressors use the same valve. The stated features and notes point to a particular compressor family, so it is worth confirming the compressor tag, the valve style, and the pressure reference before fitting.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number CPX021 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Air Conditioning Compressor Control Valve. Part number CPX021 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number CPX021, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a air conditioning compressor control valve in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN CALAIS, HOLDEN CALAIS 1997, HOLDEN CALAIS 1998, HOLDEN CALAIS 1999, HSV GTS, HSV GTS 2000. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by matching part number CPX021, Delphi compressor details, and the listed V5 / 41 PSIG application information against the vehicle’s fitted compressor before buying.
