Oxygen cryogenic pressure regulator DONMET RKK-17

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.
