A/C Expansion Valve 475-2099 - Function: Regulates refrigerant flow into the evaporator based on system pressure and temperature to maintain proper superheat and stable cooling. - Benefits: Improves cooling efficiency, reduces compressor cycling, prevents evaporator icing and floodback, ensures reliable performance in compatible A/C systems. - Compatibility: Designed for automotive air conditioning systems that specify expansion valve part 475-2099. Verify fit with vehicle year, make, model and service documentation. - Size and material: Standard automotive expansion valve size. Material and seals are defined in the manufacturer data sheet for part 475-2099. Refer to the official specs for exact dimensions and composition. - Performance: Delivers precise, responsive refrigerant flow control across typical operating ranges for automotive A/C, supporting consistent evaporator temperatures. - Use scenarios: 1) Replacing a faulty expansion valve in an in-service vehicle to restore normal cooling performance. 2) Installing in a rebuilt or new A/C system that requires model 475-2099 expansion valve to meet spec. 3) Performing routine A/C service to maintain evaporator efficiency and prevent icing or abnormal cycling.
