Application and Buying Notes

When comparing this valve to your existing part, the most useful checks are the part number TXX3540, the 1.5 ton rating and the fitting sizes. The inlet is listed as #6, the outlet as #8, and both suction connections are #10, so matching hose and line sizes matters before fitment is attempted.

The application references point to Case, Caterpillar, John Deere, Komatsu and New Holland machinery, but only within the broad ranges supplied. Where a machine has multiple AC arrangements, the safest approach is to confirm against the original valve, the part number and the measured connection dimensions before purchase.

If the existing valve has been removed or the markings are unclear, compare the HVAC line sizes and the mounting style on the machine before ordering. In AC work, matching the part number and connection layout is usually more reliable than relying on model name alone.

The one year warranty applies to the supplied valve, but it does not replace fitment checking. Confirm the system uses a block pad TX valve in the 1.5 ton configuration and that the fitting arrangement matches before installation proceeds.

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 TXX3540 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.

Denso Air Conditioning TX Valve Block Pad 1.5 Ton. Part number TXX3540 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TXX3540, 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 tx 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.

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 compatibility using part number TXX3540, the 1.5 ton block pad configuration, and the listed fitting sizes before ordering. Application references are helpful, but final fitment should always be checked against the original valve and the machine’s AC connection details.
