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.
