Frequently Asked Questions

• Is the orifice interchangeable?
  Yes, the TE2 body supports orifice sizes 01 to 05 for capacity adaptation.
• Why external equalization?
  It compensates for evaporator pressure drop and helps maintain accurate superheat control.
• Can this valve be used with other refrigerants?
  No, this model is calibrated exclusively for R134A and R513A.
• Purpose of the capillary tube?
  The 59 inch capillary tube transmits sensing bulb data to the valve for responsive superheat adjustment.
