3-Way Electric Coolant Valve
NFEL-3-25-24-C02
The electric water valve serves as the “intelligent control hub” in modern automotive thermal management systems. By precisely regulating the flow direction and rate of coolant, it maintains the vehicle’s thermal balance under various operating conditions.
Within the engine cooling circuit, the electric water valve functions as a critical control node connecting components such as the engine, radiator, and heater core. Its primary task is to accurately adjust coolant paths and flow rates based on real-time vehicle operating conditions. The control logic follows a complete closed-loop process: “signal acquisition – command execution – status feedback.”

The electronic three-way valve is a core electronically controlled flow-diverting component within the liquid-cooling thermal management system of new energy vehicles. It operates in conjunction with electronic water pumps, PTC heaters, HVAC units (for heating and defrosting), and battery cooling plates to regulate the flow path of the vehicle's coolant circulation system, thereby overcoming the limitations of traditional mechanical thermostats, such as the inability to achieve precise temperature control or switch between multiple circuits.
Compared to configurations using multiple independent two-way valves, a single electronic three-way valve streamlines the layout of vehicle coolant lines and connectors, saves chassis installation space, and reduces assembly and material costs for manufacturers. By utilizing precise coolant flow distribution logic, it enables vehicle-wide waste heat recovery and zoned thermal control, effectively lowering the thermal management system's energy consumption; it is an essential component in integrated thermal management solutions for new energy commercial vehicles and construction machinery.
The valve series offers the following core advantages:
1. Excellent sealing performance with minimal leakage rate
2. High regulation accuracy with linear control characteristics
3. Fast response speed with precise execution
4. Long service life suitable for high-frequency switching applications
5. Pressure and corrosion resistance adaptable to complex media environments
6. Low power consumption with energy-saving features
7. High waterproof rating suitable for demanding automotive operating conditions
