Emerson Process Management has released the new Fisher Type N863 Snappy Joe Emergency Shutoff Railcar Valve with up to twice the flow rate of the previous N562, offering a significant reduction in propane railcar loading/unloading time.
The Fisher railcar valve was originally developed more than 30 years ago and is the first and only emergency shutoff valve (ESV) specifically designed for railcars in the propane industry. It can be used with most compressed gases such as propane, anhydrous ammonia, natural gas liquids and aerosols.
The new N863 design greatly increases flow capacity, up to 1563 litres per minute (413 GPM) versus 757 litres per minute (200 GPM) for the N562, depending on system piping and flow capabilities. The N863 valve seals are available in Nitrile, Neoprene, Kalrez™ (FFKM), Teflon™ (PTFE), Viton™ (FKM) and EPDM to provide broad application versatility. UL Listing for the N863 is expected in 2014.
