Hydrogen Overflow Valve - Series 493
- The 493 series includes two different designs – Design I and Design III – that are specifically tailored to various installation situations, pressure ranges and operating conditions.
- Whether in hydrogen compression, pump protection or gas liquefaction – the 493 series is the optimal solution for demanding high-pressure applications.
- Pressure ranges between 50 to 1000 bar
Hydrogen Overflow Valve - Series 493
- With its precise function, flexible installation and exceptional durability, the 493 series sets new standards in high-pressure protection.
- Companies that prioritise maximum operational safety and efficiency benefit from a reliable overflow valve that works optimally even under extreme conditions.
Key features
- Design I covers a pressure range from 50 to 500 bar and has a rotatable outlet hub that allows for flexible installation.
- By contrast, design III is designed for pressures up to 1000 bar and is particularly suitable for robust applications.
- With a fixed angle housing, design III is back pressure compensated up to 500 bar, ensuring particularly stable pressure control even in demanding environments.
- While design I impresses with a wide temperature range of -196 °C to +200 °C, design III is optimised for operating temperatures between -10 °C and +150 °C.
- The robust stainless steel construction of both designs also ensures high corrosion resistance and a long service life, even under demanding conditions.
Applications
- Typical applications for the high-pressure overflow valve can be found in pump protection, hydraulics of diaphragm compressors and technical gas compression.
- It plays a particularly important role in hydrogen applications, CO₂ extraction processes and cryogenic high-pressure systems, where reliable pressure relief is essential.
- Series 493 is also used in chemical and petrochemical industrial processes and high-pressure storage.

Goetze KG Armaturen
For over 70 years, Goetze KG Armaturen has been manufacturing sophisticated high-performance valves and fittings for media under pressure: liquids, air, gases and vapours. The family-owned company, which is based in Ludwigsburg, has made themselves a reputation worldwide with their high level of quality "Made in Germany". Goetze is your partner regarding safety (valves). We assure the handling of hydrogen from the retrieval to the application – either in the electric part of the process or at the hydrogen filling station for vehicles. We protect filling processes, which are under high pressure or the storage of liquid hydrogen in tanks.
