Themostatic Expansion Valve 1/2-1 Ton MPN:EC-A-SZ
The thermostatic expansion valve is an essential component within cooling systems managing flow rates automatically regulating pressures while maintaining preset temperature settings allowing consistent system performance regardless of the load, which varies significantly between light & heavy applications like automobiles. Its design contains a bulb containing temperature sensing liquid that expands or contracts according to engine coolant demands; hence, when the driver depresses accelerator pedal causing engine revolution increases generating more heat requiring extra coolant, valve will modulate flow accordingly enabling an air conditioner capable of handling between 1/2 to a ton cooling capacity making it suitable for light vehicles where load requirements fluctuate continuously ensuring comfort within diverse climate conditions.
