Electronic Heater Control Valve



 

Thermotion’s Electronic Heater Control Valve consists of either a 2-port or 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 Electronic Heater Control Valve 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 heater/evaporator core to reduce the space requirements. In some assemblies the required space can be reduced by as much as 55%.

Automotive Heater Control Valve

2-port in-line valves come with either 5/8" or 3/4" 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.

Suitable for a variety of applications, these valves are ideal in mobile climate control systems, replacing vacuum driven valves, thereby eliminating vacuum hose routing problems along with attending vacuum leak engine problems and reducing system costs.
