Description
The Carrier EA02DZ491 is a thermostatic expansion valve. TXV is an essential part of carrier HVAC systems that use R-22 or R407C refrigerant. The TXV uses a bulb that changes its size with the change in temperature within the evaporator coil. This expansion and contraction increases or decreases the flow of refrigerant so that you gain in cooling effectiveness and efficiency of HVAC system. The TXV does not allow the evaporator coil to receive an excess of refrigerant, which may decrease the performance of the system and cause damages, it works like an intelligent valve to help your carrier HVAC system operate optimally.
