Safety Devices
The Express Fill 1,500 features a safety valve to prevent over pressurization of the vessel. The safety valve (SV-1)
relieves pressure when it exceeds the maximum operating pressure of the vessel. The valve reseats when pressure drops
below this point. In addition, the primary safety valve is supported by a secondary relief device consisting of a rupture
disc (R-1). The rupture disc requires replacement in the event a safety valve malfunctions and allows vessel pressure to
reach the burst pressure rating of the disc.
A diverter valve and dual relief valves along with rupture discs may also be ordered as an option.
