Advanced Distributor Products 165616602A – TXV Kit, Non-Bleed HP-A/C (R410A, 3.5–5 Ton)

The ADP 165616602A is a high-precision, genuine OEM Thermostatic Expansion Valve (TXV) kit specifically engineered for Advanced Distributor Products (ADP) evaporator coils. As the primary metering device for your air conditioner or heat pump, this valve modulates the flow of R410A refrigerant based on the cooling load. By maintaining the perfect balance of superheat, it ensures your system operates at peak energy efficiency while protecting the compressor from liquid slugging.

Technically designed for versatility, this kit is rated for 42,000 to 60,000 BTU (3.5–5 Tons) applications. It features a non-bleed port design, which maintains system pressure during the "off" cycle to improve SEER ratings and provide faster cooling upon startup. As a Heat Pump (HP) compatible valve, it includes an internal check valve that allows refrigerant to flow in reverse during the heating cycle, making it a universal solution for both straight-cool and heat pump split systems.

Key Features and Function:

  • Precision Metering (42-60k BTU): Optimized for large-tonnage 3.5, 4, and 5-ton evaporator coils.

  • Non-Bleed Efficiency: Improves seasonal energy efficiency by preventing refrigerant migration when the compressor is idle.

  • Heat Pump & A/C Compatible: Integrated internal check valve allows for seamless operation in both heating and cooling modes.

  • Complete Bolt-On Kit: Designed for mechanical installation, typically requiring no brazing for the valve body itself.

Product Details and Key Specifications:

  • Part Number: 165616602A (Replaces 65616602)

  • Manufacturer: Advanced Distributor Products (ADP)

  • Part Type: TXV Replacement Kit (External Equalizer)

  • Refrigerant: R410A

  • Capacity: 3.5 to 5.0 Ton (Nominal)

  • Fitting Type: Mechanical Chatleff / Threaded

  • Shipping Weight: 1.5 lbs

🛠️ HVAC Depot Pro Tip: The "Chatleff" Connection

When installing the 165616602A, ensure the Teflon O-ring is seated perfectly within the Chatleff fitting before tightening. Over-torquing can crush the seal and cause a slow refrigerant leak, while under-torquing won't engage the seal. Also, always use a backup wrench on the valve body to prevent twisting or kinking the delicate copper equalizer line during installation.

Cross-Reference & Compatibility:

The 165616602A is a direct replacement for:

  • ADP Numbers: 165616602, 65616602, 916602

  • Coil Compatibility: Fits ADP "C" and "F" series evaporator coils used with Lennox, Rheem, Goodman, and other major brands.
