Advanced Distributor Products 167828101a R454B Txv 1.5-3 Ton

Product Description

The ADVANCED DISTRIBUTOR PRODUCTS 167828101a is a bleed-style, non-adjustable thermostatic expansion valve (TXV) designed for use with R454B refrigerant in residential and light commercial heat pump and air conditioning systems. Covering a capacity range of 1.5 to 3 tons, this TXV meters refrigerant flow into the evaporator coil to maintain proper superheat, protecting the compressor and maintaining system efficiency. The bleed-style design allows a small amount of refrigerant to bypass the valve seat, which aids equalization during off-cycles. Installation is performed by licensed HVAC technicians as part of a coil replacement or refrigerant system service.

This valve is intended for R454B refrigerant systems in the 1.5 to 3 ton capacity range, covering heat pump and straight-cool air conditioning applications. R454B is an A2L lower-global-warming-potential refrigerant increasingly used in new residential split-system equipment. This TXV is suited for evaporator coil assemblies requiring a factory-style, non-field-adjustable valve where consistent, fixed superheat settings are specified by the equipment manufacturer.

Key Features

• Rated for R454B refrigerant, an A2L low-GWP alternative refrigerant
• Covers 1.5 to 3 ton system capacity range
• Bleed-style design assists pressure equalization during off-cycle
• Non-adjustable configuration maintains factory-set superheat without field modification
• Compatible with both heat pump and straight-cool AC applications

Compatibility

Designed as an OEM-style replacement TXV for R454B heat pump and air conditioning evaporator coil assemblies in the 1.5 to 3 ton capacity range. No specific model compatibility data was provided in the product input; verify fitment against the original equipment documentation before installation.

Installation Notes

This component is installed by EPA Section 608 certified HVAC technicians. Recover all refrigerant from the system before removing the existing TXV, following applicable EPA and local regulations for A2L refrigerants. Ensure the system is fully depressurized and de-energized before beginning work. Verify that the replacement valve orientation, connection sizes, and refrigerant designation match the original equipment specifications before brazing or connecting the new valve.
