The Sporlan Controls 109906 Thermostatic Expansion Valve is used to control the flow of refrigerant to the evaporator coil of the cooling equipment in HVAC systems. The valve is made with a 1/8-ton capacity with R404A refrigerant with a 1/8 x 3/8 ODF connection between the liquid line and the evaporator inlet. It is placed in the refrigeration loop where it continually controls the distribution of refrigerant needed for stable cooling and heat exchange. This liquid form that is flowing through the valve is subjected to a moderate pressure reduction, which enables it to expand to the evaporator section used in HVAC systems.
