Shut-o ball valve

Type GBCH 6s to GBCH 42s

Refrigerant:

R744 (CO2)

009R8516

Temperature range:

-40 °C – 100 °C / -40 °F – 212 °F

Max. working pressure:

GBCH 6s - 28s: PS/MWP = 90 bar / 1305 psig
GBCH 35s - 42s: PS/MWP = 75 bar / 1085 psig

Warning: Applicable to all common non-ammable 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.
