C1-01 Danfoss Thermostatic Expansion Valve TGEN10T 067N7168 Trumpet Connection for Bus AC

The C1-01 Danfoss TGEN10T thermostatic expansion valve (part number 067N7168) with trumpet port is a professional throttling spare part customized for large-capacity bus and intercity coach air conditioning systems. As one of the four core components of vapor compression refrigeration cycle, it is installed between condenser and evaporator, responsible for refrigerant pressure reduction and flow regulation, which determines the cooling output, energy consumption and safe operation of the whole bus air conditioner.

High-pressure liquid refrigerant flows into the brass valve body, turns into low-temperature low-pressure atomized refrigerant after throttling, and then enters the evaporator to absorb heat from cabin air. The external temperature sensing bulb monitors the superheat of refrigerant at evaporator outlet in real time, dynamically adjusting valve opening to match cooling load, effectively avoiding evaporator frost blockage and liquid refrigerant return that would damage the compressor.

Core Product Advantages

1. Authentic Danfoss High Precision Brass Valve Body

   Integral forged brass valve body with anti-corrosion coating, produced under Danfoss automotive-grade quality control. Ultra-precise internal valve core ensures stable and sensitive flow regulation during long continuous operation.

2. Trumpet Port Special Connection Design

   Standard trumpet port interface matches mainstream large bus AC pipeline layout, tighter sealing performance than ordinary straight ports, effectively prevent refrigerant leakage under vehicle bump vibration and high system pressure.

3. High Sensitivity Temperature Sensing Bulb & Capillary Tube

   Long metal capillary with high-precision temperature bulb can quickly capture temperature fluctuations, automatically increase or decrease refrigerant supply according to outdoor high temperature or passenger load changes, maintain uniform cabin cooling.

4. Excellent Anti-Vibration & Wide Climate Adaptability

   Reinforced fixed structure for capillary and sensing bulb, resist long-term bumpy highway driving vibration. Internal sealing accessories adapt to working temperature range of -20℃~60℃, applicable to tropical high-temperature and cold northern regions.

5. 1:1 Original Size Plug-and-Play Replacement

   All trumpet port size, capillary length, mounting dimension fully consistent with Danfoss original specification. No pipeline cutting, bending or secondary modification required during maintenance, greatly shorten overhaul labor time and vehicle downtime.

6. Compatible With Environment-Friendly R410A Refrigerant

   Suitable for R410A eco refrigerant widely used in new energy large buses, complies with international HVAC environmental protection and refrigerant emission standards.
