FAQs:

  • Q: Does this valve include the orifice?
  • A: Usually, the TE 2 body (068Z3421) is sold separately from the orifice. Ensure you select the correct orifice size for your specific capacity in the UAE.
  • Q: Why use external equalization in a Dubai project?
  • A: External equalization is necessary for systems with a significant pressure drop across the evaporator, ensuring accurate superheat sensing.
  • Q: Can I use this valve with R134a?
  • A: No, this specific model is charged and calibrated only for R404A/R507A. Using it with other refrigerants will result in poor performance.
