GBC (90 bar) / GBCT (140 bar)
Danfoss shut-off ball valves, type GBC (90 bar), GBCT (140 bar) are manually operated shut-off valves for CO2 refrigeration systems, in order to open and to shut off inner flow path by operating the valve spindle. The valves are specifically designed for intrinsic standstill security, meaning that the valves can withstand pressures normally arising when the refrigeration system is shut off, i.e. during serving or during unexpected power failure. The valve structure and materials are designed and tested specifically for use with CO2 refrigerant. GBC (90 bar) valves are designed to use in subcritical CO2 refrigeration systems. GBCT (140 bar) valves are approved for use in transcritical CO2 systems.
