The Series R/RB pressure relief valve from EnerFest offers single trim and provides full capacity at 10% overpressure for liquid, steam or vapor applications. A reversible disc provides a spare part in every valve. The nozzle threads at the top ensure nozzle/body alignment and reduce maintenance. The disc retention by ring eliminates the potential of thread corrosion and need for special maintenance tools. An adjustable nozzle ring controls the geometry of the fluid exit control chamber. The Inconel 625 bellows offers better corrosion resistance than 316L stainless steel.
