Ease of Installation:A straightforward replacement for your heater control valve, no special tools required. High Temperature Resistance:Withstands up to 105℃, ensuring durability in high-temperature environments. Precision Engineering:4-way throttle tube design for efficient water flow control in heater systems. Optimized fluid control structure ensures uniform and stable water flow, preventing localized overheating or underheating and effectively balancing the overall engine operating temperature. Regulating coolant flow direction and volume improves in-vehicle heating efficiency, shortens cold start time, and enhances driving comfort in winter., Manufacturer: ZDGsdgSY
