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 ...

A Pilot Operated Safety Valve (POSV) is a type of safety valve that utilizes a pilot pressure to control the main valve's disc, allowing for better sealing and response to fluctuations in pressure.

Many combined cycle power plants are being operated as peaker plants, rather than as baseload units. That can pose a problem for economizer safety valves. Pilot-operated safety valves offer ...
