Denso 447500-0470 A/C Expansion Valve

The Denso 447500-0470 is a thermostatic expansion valve (block type) designed for R134a refrigerant systems. It meters liquid refrigerant into the evaporator based on superheat feedback, ensuring efficient heat exchange in the HVAC unit. The valve body is constructed from aluminum alloy with stainless steel internal components for corrosion resistance. It features O-ring sealed flange connections compatible with Kubota OEM piping. This component serves as a direct replacement for Kubota part numbers 447500-0470 and T106572170. Cross-reference interchange includes aftermarket part numbers JC38004 and 4475000470. The valve is calibrated for the specific evaporator capacity of Kubota B, L, and M series tractor cabins. Installation requires evacuation and recharge of the A/C system per SAE J2788 standards. No electrical actuation or external equalizer line is required for this block-type configuration.
