Universal Air Conditioner A/C Block Expansion Valve

The Universal Air Conditioner A/C block expansion valve, also called a thermal expansion valve (TXV) or block-style TXV, meters refrigerant flow into the evaporator. It helps your automotive air conditioning system cool efficiently and consistently.

Key Features:

• Block-style design with a single body that handles both the high-pressure inlet and the low-pressure return refrigerant passages
• Senses evaporator outlet temperature and adjusts refrigerant flow to match the cooling load
• Helps maintain steady evaporator temperatures and protects the compressor by limiting the risk of liquid refrigerant returning to it
• Replacement part for worn, stuck or clogged expansion valves that cause weak cooling, icing or inconsistent vent temperatures
• Suitable for A/C repair, system rebuilds and compressor or evaporator replacement

When you replace a major A/C component, it is good practice to install a new expansion valve and a new receiver-drier or accumulator. Evacuate and recharge the system according to the equipment manufacturer's specifications. Choose the child item that matches your system's connection and refrigerant requirements.
