Frequently Asked Questions

• Is the orifice interchangeable?
  Yes, supports 01–05 orifice sizes for optimized capacity.
• Why external equalization?
  It compensates for evaporator pressure drop to maintain accurate superheat control.
• Can it be used with other refrigerants?
  No, this valve is calibrated exclusively for R22 and R407C.
• What is the function of the capillary tube?
  The 59 inch capillary transmits bulb temperature to the valve for responsive superheat regulation.
