Safety Valves for Hydrogen Applications
These valves can withstand set pressures up to 1100 bar
Seetru supplies safety relief valves suitable for a wide range of hydrogen applications, including hydrogen generation, fuel cells, compressors and pumps, fuelling systems, storage, pressure vessels, piping systems, and transportation.
These valves can withstand set pressures up to 1100 bar, making them ideal for use in even the most demanding hydrogen applications. Seetru’s valves are designed to open quickly and reliably when the system pressure exceeds the set pressure, allowing excess gas to escape safely. This helps to prevent damage to the system and protect personnel from injury.

Why safety valve testing and maintenance is essential
Compliance Demands Safety Valve Testing and Maintenance
Safety valve testing and maintenance are essential for:
Preventing equipment damage:
Malfunctioning valves can lead to costly overpressure incidents.
Protecting personnel:
Faulty valves pose safety risks and potential legal liabilities.
Maintaining compliance:
Regular testing meets industry standards and avoids non-compliance issues.
Optimising production:
Reliable valves minimise shutdowns and improve plant efficiency.
Invest in a maintenance program for safe, efficient, and compliant operations. Treat safety valves as crucial guardians, not just equipment.
Don't Let Pressure Build
Why Health, Safety and Environmental Compliance Demands Safety Valve Testing and Maintenance
The Pressure Equipment Directive (PED) safeguards lives and assets by setting stringent standards for designing, manufacturing, and operating pressure equipment. But even compliant equipment needs a dedicated guardian: the safety valve. Regular testing and maintenance of these critical devices are not just best practices, it is essential for ensuring optimal safety as well as optimal cost and environmental performance.
Investing in proper safety valve testing and maintenance isn’t just a legal requirement, it’s a sound business decision. It safeguards personnel, protects valuable assets, and keeps your operation compliant and productive.
