Carrier EA660004 Thermal Expansion Valve Valve

The Carrier EA660004 is a Thermal Expansion Valve that can be incorporated into any HVAC program including air conditioning and refrigeration. It is essentialin controlling the flow of refrigerant through response to temperature variations. This valve uses a bi-metallic spring where the size and shape of the spring change with the temperature. In summer, the spring opens and pushes more refrigerant through the system because it is hot. However, a low temperature leads to the contraction of the spring and therefore reduces the circulation of refrigerants. This mechanism regulates the system temperatures and enhances the rate of cooling and therefore comfort and potentially reduced energy bills.
