Car air conditioning expansion valve

The air conditioning expansion valve is a vital component that maintains the necessary pressure within the system. The refrigerant in the AC system is under high pressure, resulting in a very high temperature. The expansion valve lowers the pressure, causing the refrigerant to cool rapidly. It then passes through the evaporator, where it cools down even further. The blower fan blows air over the evaporator, which cools the airflow and keeps your car's interior nice and cool.

Because the expansion valve operates under high pressure and significant temperature differences, it is susceptible to wear and tear. When the expansion valve is worn out, your air conditioning will no longer function properly. Therefore, it's essential to have the expansion valve checked regularly and replaced promptly with a good quality valve.

Expansion valve purchase

Buying a new expansion valve is easy at Winparts. We offer a wide range of high-quality brands such as NRF, Mahle and Denso. By entering your registration number, you can easily find suitable parts for your car. The air conditioning system is pressurised, so only a mechanic with the appropriate knowledge and tools should work on it. When the expansion valve is replaced, the receiver drier is also replaced, as it becomes saturated with moisture when the AC system is opened.

You can save on material costs by ordering your parts from Winparts and having them fitted by an experienced mechanic. You can also contact Winparts for other parts for your air conditioning and heating system.

The expansion valve allows the air conditioning to release pressure. If the valve is broken, your air conditioning will not cool properly.
