EXPANSION VALVES

Type ATX

GENERAL DESCRIPTION
• Application: General refrigeration and air conditioning
systems.
＊Note: S–charge valve for low temperature (−40 to 10°C),
unloading, heat pump applications, or hot gas defrost
system. CY–charge valve for extreme low temp. (−70 to
−40°C) application.
• Charge: L (Liquid) charge for refrigeration application.
G (Gas) charge for cooling application with
20°C (standard) MOP.
S (Special) charge for all purpose with 20°C
(standard) MOP.
C (Cross) charge, CL (Cross low) charge and
CY (Extream low) charge for low temp applica-
tion.
• Max. allowable pressure:
1.37 MPa {14kgf/cm2} . . (G, L, C, CL–charge) Type ATX–B

2.75 MPa {28kgf/cm2} . . . . (S, CY–charge)

• Adjustable range of static superheat:
3 to 13°C . . . . . . . . (G, L, CL–charge)
0 to 8°C . . . . . . . . . . . . (S–charge)
0 to 13°C . . . . . . . . . . . (CY–charge)
• Superheat change:
4 to 5°C (R134a) . . . . . . (L or G–charge)
2 to 3°C(R22) . . . . . . . (L or G–charge)
4 to 6°C(R134a, R22) . . . . . . (S–charge)
8 to 12°C(R22) . . . . . . . . (CY–charge)
• Rugged diaphragm element: Best for heat pump units.
