The Trane VAL07559 Thermostatic Expansion Valve is used to control the flow of the liquid refrigerant, in the evaporator in HVAC systems. This sensing bulb and internal valve mechanism regulate the flow of refrigerant according to the temperature and pressure conditions, which enables the 5-ton TXV with a 0.31 ODS x Chatleff connection to control the flow during operation in air-conditioning and heat pump elements. This liquid line is a suction line where a sensing bulb is fitted in the line, and the valve body is attached to the refrigerant piping.
