The Carrier EA36UZ168 Thermostatic Expansion Valve is used in HVAC and equipment used in air conditioning and refrigeration. It is essential in controlling the circulation of the refrigerant as a result of change in temperature. The valve works on the principle of a bi-metallic coil which gets either elongated or shortened depending on the temperature. This expansion and contraction allows the fine tuning of a valve, to control the quantity of refrigerant gas that can enter into the Cob evaporator unit. Such level of control enhances the cooling characteristics and cooling effectiveness inside the system.

  • Sensing bulb losing charge or becoming loose.
  • Frost buildup from incorrect superheat control.
  • Internal valve sticking or failing to respond to temperature changes.

Installation Steps

Step 1: Shut down HVAC system, disconnect power, and recover refrigerant using proper recovery equipment.

Step 2: Remove existing valve and clean inlet/outlet tubing and surrounding coil connections thoroughly.

Step 3: Install new valve in correct orientation, ensuring proper refrigerant flow direction alignment.

Step 4: Braze all joints using nitrogen purge to prevent oxidation and internal contamination.

Step 5: Perform leak test, evacuate system to deep vacuum, recharge refrigerant, and verify superheat and stable cooling operation.
