New railcar emergency shutoff valve increases flow capacity

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, according to the company.
 The railcar valve was originally developed more than 30 years ago. It can be used with most compressed gases, such as propane, anhydrous ammonia and natural gas liquids.
 The new N863 design greatly increases flow capacity, up to 413 gallons per minute versus 200 gallons per minute for the N562, depending on system piping and flow capabilities, the company says. The N863 valve seals are available in Nitrile, Neoprene, Kalrez, Teflon, Viton and EPDM to provide broad application versatility. A UL listing for the N863 is expected this year, the company says.
