Trane VAL6929 Thermal Expansion Valve(TXV) R410A 3-Ton

The Trane VAL6929 is a Thermal Expansion Valve intended for use with Trane HVAC systems that use R410A refrigerant and for systems that are 3-ton rated. This is a essentialpart of the HVAC system since it works like a pressure–controlled valve that controls the amount of refrigerant within the system. The TXV uses the temperature of the refrigerant leaving the evaporator coil to control and measure the refrigerant flow. This control is precise enough to enhance cooling effectiveness and to stabilize preferred temperatures Hence enhancing the effectiveness of your heating and cooling thus may reduce energy usage.
