Fisher Type 63EGLP bulk storage tank relief valve

The Fisher Type 63EGLP bulk storage tank relief valve is designed to be used on 110,000 litre and larger propane tank applications. The Type 63EGLP offers multiple benefits over traditional multiport relief valves, including a 40% increase in relief capacity, a 20% weight reduction for easier installation, and reduced maintenance costs. The UL-certified relief valve is approved for bulk propane storage relief installations compliant with NFPA 58.

The valve achieves significantly greater relief capacity than a traditional multiport relief by incorporating a highly accurate pilot controlling valve. This pilot controlling valve has been used for decades in petrochemical and natural gas applications and has proven to be both accurate and highly reliable. The 40% capacity increase translates into significant savings for tanks of 340,000 L or larger, requiring only two Fisher Type 63EGLP’s versus three traditional multiport relief valves. Installation is simplified due to a 20% reduction in weight and a reduction in overall size in comparison to multiport relief valves, along with an included lifting sling.

The device’s dual-pilot design provides high accuracy relief and the ability to service one pilot while the other pilot controls the relief valve for uninterrupted relief protection, helping to minimise maintenance time and costs.
