Trane VAL1155 Thermal Expansion Valve R-22

The Trane VAL1155 is a thermal expansion valve for use in HVAC systems that use R-22 refrigerant. It is the most essentialpart of refrigerant circuits and it regulates the passage of refrigerant based upon the evaporator coil temperature. The TXVs restrict the flow of refrigerant when the coil temperature falls so that the ideal pressure in the evaporator is maintained. It guarantees effective system operation and prevents overcooling. The Trane is compact and is made of durable brass for dependable performance and is well suited for systems up to 5 tons. The inlet and outlet connection sizes are 3/8" and 1/2", respectively.
