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.
GBC / GBC E / GBC L
Danfoss shut-off ball valves, type GBC, are manually operated shut-off valves for refrigeration systems, in order to open and to shut off inner flow path by operating the valve spindle.
The GBC valves are used in liquid, suction and hot gas lines in refrigeration and air conditioning systems.
The GBC bi-directional ball valves can be delivered with or without external access port.
The valves have one-piece wire seal cap to prevent unintentional cap removal or tampering between services.
There are 3 different ranges, valid for different types of refrigerants, system sizes and made with different materials: GBC and GBC E in brass, GBC L in stainless steel.
OFB
OFB shut off ball valves are a suction solution for superior reliability of oil-free system featuring Danfoss Turbocor® compressors.
OFB shut off ball valves efficiently prevent from refrigerant migration during extended standby periods and therefore, from the risk of liquid slug upon compressor restart.
