For the past 15 years, pilot-operated safety relief valves (POSRVs) have effectively and reliably protected economizers on Section I power boilers in overpressure situations, working in tandem ...

Safety relief valves are relatively maintenance-free devices. Even so, it is recommended that a periodic inspection of these devices be done every six to 12 months. A visual inspection should be made ...

Installation of relief valves in parallel with the safety valves on deaerator installations can prevent unnecessary activation and ‘chattering’ of the safeties from minor upsets in pressure control, e ...

LESER safety relief valves are optimized to feature a simplified design with fewer components, resulting in less down time, fewer spare parts and lower maintenance costs.

Pressure relief valves are critical components in high‐pressure systems across diverse industrial sectors, including energy, nuclear, and chemical processing. Their dynamic behaviour ...

On March 6, the U.S. Chemical Safety and Hazard Investigation Board (CSB) issued a new Safety Alert titled “Hazards Posed by Discharges from Emergency Pressure-Relief Systems.” The alert highlights ...

Testing a relief valve at the wrong time could damage the spring—or worse, take your boiler offline. In this installment of Weekly Boiler Tips we cover the safest testing frequencies and what you need ...
