ATX-12420, 12500DHGCL (ATX-71160) Lugong expansion valve function introduction

Summary: Because of the built-in diaphragm structure in the body, the ability to change is possible.

When the evaporating temperature is below 20 ℃, the S filling method is suitable for unloading mechanism attachments, heat pump air conditioners, etc.

General specifications: Maximum working pressure: 2.8mpa (S, SL, CY filling)

3.3MPa (R407C is filled with S)

1.4MPa (G, L, C, CL filling)

Maximum temperature of the main body; 80 ℃

Maximum temperature of temperature sensing package: 40 ℃ (L, C, CL, CY filling), 80 ℃ (G filling), 120 ℃ (S filling)

Exquisite superheat adjustment range: 3-13 ℃ (G, L, CL filling), 0-13 ℃ (CY filling), 0-8 ℃ (S filling), 1-7 ℃ (for R404A, S, SL filling) Clockwise rotation increases by about 0.007MPa / rev

The model depends on the specifications.
