C1-17 Emerson TCLE Thermostatic Expansion Valve 3.5T/5.5T/7.5T for Medium Bus AC

The C1-17 Emerson TCLE thermostatic expansion valve is a multi-tonnage throttling core specially designed for 7–10m medium-sized bus and shuttle air conditioning systems. As a core component of vapor compression refrigeration cycle, it is installed between condenser and evaporator to finish refrigerant depressurization and flow regulation, directly controlling cooling efficiency and system safe operation of medium bus HVAC units.

This Emerson TCLE valve covers three mainstream cooling capacities (3.5T, 5.5T, 7.5T) to match different power rooftop AC units for medium coaches. The long copper capillary temperature sensing bulb monitors evaporator outlet superheat in real time, automatically adjusting valve opening to balance refrigerant supply, effectively prevent evaporator frost blockage and liquid return damage to medium-displacement compressors.

Core Product Advantages

1. Genuine Emerson Industrial-Grade Brass Valve Body

   Integral forged brass valve body with anti-corrosion coating, manufactured under Emerson strict vehicle component standards. Precision internal valve core delivers consistent, sensitive flow adjustment under long-hour continuous operation.

2. 3 Multi Tonnage Specs Unified Platform Design

   One product series covers 3.5T, 5.5T, 7.5T three mainstream medium bus cooling demands, greatly reduce spare part stocking types and inventory capital occupation for repair shops and bus fleets.

3. Long Capillary High-Sensitivity Temperature Sensing System

   Extended copper capillary tube with large-area sensing bulb captures subtle refrigerant temperature changes instantly, dynamically matching cooling load fluctuations caused by passenger number and outdoor high temperature, maintaining uniform cabin cooling effect.

4. Strong Anti-Vibration & Wide Temperature Adaptability

   Reinforced fixed structure for capillary and sensing bulb, resists continuous bump vibration during urban and highway driving. Internal sealing components adapt to -20℃~60℃ full climate range, fit tropical high-temperature and cold low-temperature regions.

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

   All pipe interface sizes, capillary length and mounting dimensions fully comply with Emerson TCLE factory specs. No pipeline cutting, bending or secondary modification required during maintenance, drastically shorten vehicle overhaul downtime.

6. Compatible With Eco-Friendly R410A Refrigerant

   Supports R410A environmental refrigerant widely used in new energy medium buses, conforming to global HVAC refrigerant emission and environmental protection standards.
