The valves provide a means of shutting off gas in the event of a hose rupture or piping break at the transfer area to avoid a large scale loss of LP-Gas or NH3. The valves can be manually opened and closed at the installed location or closed remotely by either cable, air or nitrogen. A remote operating actuator is also available. Pneumatic Operation – Remote pneumatic closure is available with Type P327D release. Depending upon valve inlet pressure, a minimum supply pressure of 30 to 70 PSIG on the P327D allows the valve to be latched in the open position with manual closure possible at the valve. Loss of supply pressure to the cylinder permits the ESV to close. Air, nitrogen, or CO2 can be used for the cylinder supply source. Maximum inlet pressure to the cylinder is 125 PSIG (8.6 bar). Operating Temperature Range = -40°F to 212°F (-40° to 100°C). Opening and closing of Snappy Joe® ESVs from a remote location can be done by using Type P539A air cylinder. Depending upon valve inlet pressure, a minimum supply pressure of 30 to 70 PSIG to the cylinder opens the valve. Air, nitrogen, or CO2 can be used for the cylinder supply source. Using the MINI-1 with the P539A allows the valve to be opened or closed remotely.

The N863 High-Flow version provides double the flow rate of the existing Emergency Shutoff Valves & has a female coupling allowing flexibility, as nipple lengths are field selectable based on specific application requirements. Typically three of the valves are used; two on liquid lines & one on the vapour line. These Emergency Shut-off Valves can also be utilized in non-railway plant designs, providing additional safety shut-off control!
