Description
The Trane VAL18894 5-Ton Thermal Expansion Valve (TXV) R410A regulates refrigerant entering the evaporator according to changing system conditions. Its sensing mechanism responds to temperature conditions and adjust the valve opening to control refrigerant delivery. Connected to refrigerant lines and the evaporator circuit the valve manages refrigerant expansion in HVAC systems while maintaining the required flow through the cooling section. This metering action regulates refrigerant supply as operating conditions change supporting controlled evaporator performance and maintaining the required refrigeration cycle.
