For liquid oxygen -196°С.
The pressure regulator is used as part of cryogenic cylinders, vaporizers or converters.
The single-stage cryogenic pressure regulator RKK-17 is designed to reduce and regulate the pressure of cryogenic liquid and automatically maintain a constant set working pressure.
All parts of the cryogenic regulators are made of materials compatible with cryogenic temperatures (up to -196°С) and are cleaned for operation with liquid oxygen in accordance with the CGA G-4.1-2009 standard.
– The reducing valve, made with a PTFE insert, ensures reliable operation at temperatures up to -196°C.
– The reduction unit filter prevents foreign particles from entering the reducer.
