Denso 475-2046 A/C Expansion Valve

Denso New Expansion Valve 475-2046

Denso New Expansion Valve 475-2046 is a block-style A/C expansion valve that regulates refrigerant flow through the evaporator and helps maintain proper separation between the low and high sides of the air conditioning system. It is built for direct replacement use on select Subaru, Scion, and Toyota applications, including Legacy, Outback, xA, and Echo models.

The Denso New Expansion Valve line focuses on correct calibration for vehicle-specific A/C systems. When the valve is out of spec, evaporator performance can drop and icing can occur, which can lead to costly system damage. Part number 475-2046 is engineered for the application-specific control needed in these systems.

• Block valve design for automotive A/C refrigerant metering
• Controls liquid refrigerant flow into the evaporator
