Thermotion Heater Control Valves are designed and manufactured to meet O.E.M. requirements. Our valves provide ONOFF or bypass of engine coolant flow through the heater core of vehicle heatingdefrost systems.

2-port in-line valves come with either 58" or 34" ID hose connections. Valves can be either power to open, spring return closed or power to close, spring return open. Units are powered by Thermotion's unique Electro-Thermal Actuator technology in 12 or 24 volt configurations.

Thermotions Electronic Coolant Control Valve pn 354-69494 consists of a 4-port bypass butterfly water valve powered by an electric actuator. The ECC controls coolant flow with an electrical signal. An integral position feedback potentiometer is included. The ECC is ideal for use with a space- efficient HVAC system that eliminates the blend air temperature door and controls the discharge air temperature by modulating coolant flow to the heater core. This allows the heater and evaporator cores to be installed face to face, or the use of an integral heaterevaporator core to reduce the space requirements. In some assemblies the required space can be reduced by as much as 55%.
