The TXV regulates refrigerant flow into the evaporator, controlling pressure and refrigerant volume so the air-conditioning system can absorb cabin heat effectively and maintain stable cooling performance.\u003c\/p\u003e\n\u003ch3\u003eMaterials \u0026amp; Workmanship\u003c\/h3\u003e\n\u003cp\u003eThe valve body is precision-machined from lightweight metal for accurate refrigerant passage geometry, corrosion resistance and efficient thermal response. Internally controlled flow passages meter refrigerant through the A\/C circuit while the compact block-style construction provides a rigid sealing surface for the connected refrigerant lines.\u003c\/p\u003e\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe expansion valve reduces refrigerant pressure before it enters the evaporator and meters the correct amount of refrigerant according to system demand. A correctly functioning TXV helps the evaporator operate at the proper temperature, supports consistent vent cooling and prevents inefficient refrigerant flow through the circuit.\u003c\/p\u003e\n\u003ch3\u003eFitment \u0026amp; Reference\u003c\/h3\u003e\n\u003cp\u003ePart number: \u003cstrong\u003e673003704\u003c\/strong\u003e. This TXV kit is used on selected Maserati Ghibli, Levante and Quattroporte M156 applications and replaces earlier reference 673000087 in relevant catalogues.
