Description
The Trane VAL12857 Expansion Valve is used to control the flow of refrigerant to ensure the correct pressure and temperature ratio in the HVAC systems. It has 0.25 ODS inlet and 0.38 ODS outlet connections that meter the refrigerant according to the load demand and evaporator conditions. The valve assists in maintaining steady heat of liquids and maximizing heat transfer. It will assist in maintaining efficient cooling operation, stable temperature control and reliable operation of air-conditioning, and refrigeration circuits when the system is operating normally by coordinating with compressors, evaporator coils ,and control parts.
