The Anderson Greenwood Series 5100 pilot-operated pressure-relief valve is designed for over-pressure protection of economizers in fossil-fired power plants.

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 ...

Relief valves do the same job as safety valves, but they also smoothly and continuously modulate flow to keep pressure from exceeding a preset level. A relief valve is normally closed until the ...

DMS also holds the ASME "UV" stamp for the manufacture of pressure vessel pressure relief valves, as well as ISO certifications. The facility expects to receive CQSIQ and PED certification in late ...

It’s called the pilot-operated relief valve, and it sits atop the pressurizer attached to the Unit 2 reactor of Three Mile Island. It is often referred to as PORV, and something went very wrong ...

“Pressure relief valves positioned on either the suction or discharge sides are not notably distinct, aside from their designated pressure ratings,” said Aschow. “Currently, there exists a substantial ...
