Bulk storage tank relief valve for propane tanks

15 April 2014

Emerson Process Management has released the new Fisher Type 63EGLP Bulk Storage Tank Relief Valve, typically used on 100,000 litre and larger propane tank applications. The Type 63EGLP offers a range of 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 is said to achieve greater relief capacity than a traditional multiport relief by incorporating an accurate pilot controlling valve. This pilot controlling valve has been used for many years in petrochemical and natural gas applications where is has been proven to be accurate and reliable. The 40% capacity increase translates into significant savings for tanks of 300,000 litres or larger, requiring only two Fisher Type 63EGLP's instead of three traditional multiport relief valves. Installation is also 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 Type 63EGLP’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.With an increased capacity, ease of installation, reduced maintenance costs, and a history of decades of accurate, dependable service in the petrochemical industry, the 63EGLP provides great value to the propane industry.
