Danfoss GBCH shut-off ball valves designed for R744 (CO2) refrigerant to use in subcritical refrigeration systems. GBCH are manually operated shutoff valves for CO2 refrigeration systems, in order to open and to shut off inner flow path by operating the valve spindle. They 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.
Danfoss GBCH shut-off ball valves intended for work in a temperature range from -40 to +100°С.
Maximum pressure is 75-90 bar. The compact valve construction allows for easy installation and maintenance, and an indicator on the top of the spindle shows the degree of opening.
GBCH valves have pre-drilled threaded holes for panel mounting.
The spindle design is resistant to damage.
