The element inside the housing provides an extinguishing barrier to the ignited vapor mixture by absorbing heat from the flame. The Model 7A00 is used as an independent safety system to ensure explosion protection. 7A00 flame arrestors are designed on the principle of "quenching gap".
The crimped SST metal element allows vapor to pass through in order to allow a vessel to breath, yet prevents the propagation of a flame from the exposed side to the protected side.The Model 7A00 is designed, manufactured, and tested according to Directive 2014/34/EU (ATEX95) and ISO 16852. The element design is bidirectional and available for horizontal or vertical installations.

The Model 5100 has a pilot operated pressure side which permits tank operating pressures closer to the maximum allowable operating pressure. This provides a more positive control over vapor generation inherent in fluids with higher vapor pressures. The vacuum side of the vent is weight loaded and allows intake of air when necessary to remain within the vacuum design rating of the tank.
When the tank pressure reaches the setpressure of the pilot, the pilot assembly opens eliminating the additional downward force on the pallet assembly. The "full" tank pressure pushing upward on the palletassembly will cause the main valve to open. Full flow willbe achieved at no more than 10% overpressure.
Internal trimdesign allows the same basic unit to cover a broad range of pressure settings. Performance approaches that of competitive pilot-operated designs in the basic construction. Applied primarily in clean gaseous or liquid services. Truly a "DO-ALL" pressure regulator. The "DO-ALL" design allows application of all types of clean fluids.
The Model 1078 is a pilot-operated valve, specifically designed to reduce blanketing gas losses on lowpressure storage tanks. The simple design, increases reliability and lowers maintenance cost. On many low-pressure storage tanks the operating range is very low, which makes blanketing and venting system selection/design a challenge for the engineer.
