Description

This Genuine OEM-Quality Thermo King Expansion Evaporator Valve (Part Number: 61-4091 / 614091) is a high-performance thermal expansion valve (TXV) engineered to optimize climate control efficiency inside heavy-duty sleeper berths. Designed specifically to regulate refrigerant flow within the evaporator core of Thermo King TriPac and Tri-Pac Evolution Auxiliary Power Units (APUs), this valve maintains the exact balance of cooling pressure regardless of external summer temperatures. It is manufactured from premium corrosion-resistant brass and stainless steel alloy to prevent clogging or mechanical sticking from continuous HVAC cycling. Replacing a failing or stuck expansion valve eliminates common reefer climate issues such as evaporator coil freeze-ups, erratic cab cooling, and low-refrigerant symptoms, ensuring maximum driver comfort during long-haul layovers.
⭐ Key Features & Benefits
  • Precision Refrigerant Regulation: Accurately meters liquid refrigerant into the evaporator core to maximize auxiliary A/C system performance.
  • Heavy-Duty Brass Construction: Formulated with premium metal alloys for superior temperature resistance and structural longevity under constant pressure.
  • Direct-Fit APU Configuration: Manufactured to mirror exact original factory spatial footprints for a clean, leak-free mechanical installation.
  • Prevents Evaporator Freeze-Ups: Maintains proper system head pressures to stop frost accumulation and airflow blockages over the coils.
  • Optimized Driver Comfort: Ensures deep, reliable cab cooling output from your TriPac unit while reducing fuel consumption and engine load.
🔧 Uses / Applications
  • APU Climate Control Maintenance: Replaces failed, leaking, or internally contaminated thermal expansion valves inside the cab's HVAC box.
  • TriPac Evolution Service Overhauls: Essential replacement hardware during comprehensive auxiliary air conditioning recharges or compressor swaps.
  • Preventative Fleet Upgrades: Installed by fleet mechanics to clear erratic auxiliary cooling cycles and keep drivers comfortable without excessive tractor idling.
  • High-Margin Liquidator Inventory: Highly sought-after hard part for commercial transport operators, semi-truck repair facilities, and industrial liquidators.
