Features and Benefits
·Extra heavy construction provides long life.
·Top guided disc assembly incorporates resilient seal in seating area.
·An isolation diaphragm protects working parts from corrosion caused by discharged liquid.
·Pivot between disc and spring corrects for misalignment and compensates for spring side thrust.
·These safety relief valves serve the dual purpose of relieving (1) overpressure created by thermal expansion under normal ?on and off? firing conditions, and (2) overpressure in the form of water or steam created in over-firing due to failure of electrical or other controls.
