Gates EHV120 HVAC Heater Control Valve

Gates EHV120 Electric Heater Control Valve

The Gates EHV120 Electric Heater Control Valve is an OE Exact replacement for vehicles that use electronically controlled coolant flow for cabin heat and thermal management. It is built with a plastic housing and two 10 mm inlet ports to match the original coolant routing on select Hyundai Sonata and Kia Optima applications.

Gates’ Electric Heater Control Valve line addresses modern HVAC and thermal systems that rely on electric coolant control rather than a traditional manual valve. On supported vehicles, this valve helps regulate coolant movement through the heater core and, in some applications, supports transmission coolant control functions.
