Fisher® Type 63EGLP relief valve provides superior overpressure protection for large bulk plant applications. Steel and stainless steel construction allows for use on both LPG and Anhydrous Ammonia storage tanks. Bringing advanced technology from the petrochemical industry, the Type 63EGLP provides precise and controlled pressure relief in an emergency situation to protect your pressure vessel while simultaneously limiting the amount of product discharged to the atmosphere.
Tight fitting UV resistant caps are standard on all constructions, along with a load-rated lifting sling to assist with lifting and installation. End connections are standard 4 in. CL300 RF bolt patterns. Fisher Type 63EGLP relief valve provides the industries most advanced relief technologies. The accuracy and repeatability of pilot-operated pressure regulation excercises precise control during relief situations without relying on last-generation pop-style relief mechanics. The Fisher Type 63EGLP is the evolutionary leap forward in bulk plant pressure relief combining safety, durability and serviceability into one superior package.
