The Parker Hannifin Corporation is the manufacturer of the D4521 Safety Relief Valve 1-1/4x1-1/2 Inch, which provides relief on excess pressure or temperature surges in piping systems. The valve's primary aim is to prevent uncontrolled release and burst due to overpressure by releasing pressure through the vent at an adjustable rate to atmospheric pressure. D4521 is engineered with a robust construction featuring bronze body and stem, NBR sealing elements, and a spring-operated disc that opens under excess pressure to divert flows. It caters to numerous industries like power generation, petrochemicals, water treatment, chemical, oil & gas or heating ventilation air conditioning (HVAC). D4521 Safety Relief Valve offers reliability in various applications where overpressure can be hazardous, offering a safe and controlled method of venting to protect valuable equipment from damage.
