Themostatic Ex Valve 1/3 to 1/2 Ton MPN:SCE-AA-VZ
The Thermostatic Expansion Valve (1/3 to 1/2 ton) is an essential component for air conditioning and refrigeration systems that require precise temperature control, particularly those operating at low capacities such as in residential or small commercial settings. This valve regulates the flow of refrigerant through the evaporator coils, ensuring a consistent supply of hot or cold air while maintaining desired temperature settings and reducing energy consumption. The diaphragm type design offers easy installation, reliable operation, and minimizes refrigerant charge while offering excellent temperature control even during part load conditions. Additionally, its ability to modulate the flow rate prevents condensate back up and reduces stress on the compressor. As such, Thermostatic Expansion Valves are a cost-effective and efficient solution for maintaining precise temperature control in a wide range of cooling applications.
