The GBCH for R744 (CO2 applications) ball shut-off valves from Danfoss are manually operated shut-off valves for CO2 systems. The valves have been specially developed for system-specific downtime safety, i.e. they can withstand the pressure that builds up when the refrigeration system is switched off, e.g. during maintenance or an unexpected power failure. The structure of the valve uses materials specially designed for use with CO2 refrigerant and has been tested as such. The valves are approved for use in all system parts for which the pressure rating is below the maximum permitted operating pressure stated below. These are generally the fluid, suction and gas bypass lines.
Notes: For use with R744 as part of a secondary circuit or cascade system:
1. The design pressure for components containing the refrigerant is not lower than the designed pressure of the associated components.
2. The components has no overpressure or pressure limiting valve for which a sufficient number of valves with the necessary power would need to be installed in the refrigeration system.
3. When the refrigeration system is idle, R744 may escape via the pressure limiter valves which can make it necessary to refill the refrigerant (do not, however, remove or bypass the valve).
4. Depending on the power of the system, it may be necessary to install a sufficient number of overpressure and pressure limiter valves. There should not be any shut-off valves installed between the overpressure valve and parts or areas of the system that need to be protected.
