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 with ...

MONTVILLE, N.J.--(BUSINESS WIRE)--Marotta Controls, a rapidly growing aerospace and defense supplier, announced it has upgraded its motor operated pilot valve (MOPV) used in aqueous film-forming foam ...

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 several ...

A trend has been gaining steam: Electric, modulating, pressure-reducing valves (PRVs) are increasingly replacing traditional self-piloted regulators in steam systems. The adoption of this “smart” ...
