Refrigerant: 

R744 (CO

2

)

Max. working pressure:

GBCH 6s - 28s: PS/MWP    =   90 bar / 1305 psig

GBCH 35s - 42s: PS/MWP  =  75 bar / 1085 psig

Temperature range: 

-40 °C – 100 °C / -40 °F – 212 °F

Warning: Applicable to all common non-flammable refrigerants, excluding R717 and to 

noncorrosive gases/liquids dependent on sealing material compatibility.  

The design pressure shall not be less than the value outlined in Section 9.2 of ANSI/ ASHRAE 15 for 

the refrigerant used in the system. Only authorized persons are allowed to operate this valve, as 

closing can cause build-up of excessive pressure in the system. For the application use with R744 as 

part of a secondary loop or cascade system should refer to the datasheet for more attentions.
