Trane VAL9026 Thermal Expansion Valve(TXV), 12.5 Nom.Cap.Tons, R410A

The Trane VAL9026 Thermal Expansion Valve made for HVAC system installation with R410A refrigerant gas. It also acts as a controller of the amount of coolant that enters the evaporator coil which we can liken to the component that dissipates heat from the house. The TXV could be said to self-regulate and function like an automatic valve considering the coolant as it exits the coil. When cool refrigerant passes over the coil, the TXV opens up so that it can allow more refrigerant into the system. On the other hand, when the refrigerant gets hot after it has absorbed heat, the TXV throttltes the flow to ensure that the liquid refrigerant does not flow into the coil. This is to allow maximum flow of evaporated air together with heat transfer on the coil.
