Frequently Asked Questions
- Is the orifice interchangeable?
Yes, the valve supports orifice sizes from 01 to 05 for capacity matching. - Why internal equalization?
Best for systems with minimal evaporator pressure drop, maintaining stable superheat control. - Can this valve be used with other refrigerants?
No, it is calibrated specifically for R134A and R513A only. - What does the capillary tube do?
The 59 inch capillary transmits bulb temperature to the valve for responsive superheat control.
