The Shand and Jurs 94470 Combination Conservation Vent and Deflagration Flame Arrester is a single, easy to configure package providing for pressure and vacuum relief, as well as positive flame stop on low pressure tanks containing flammable liquids or solvents having a low flash point.
The conservation vent features cushion seated diaphragms constructed of FEP for reliability and extended service life. For high reliability, the pressure and vacuum pallets are both peripherally and center stem guided.
The unitized tube bank provides maximum flow while minimizing pressure drop. Both body and tube banks are available in numerous materials to meet the requirements of your site.
Temperature monitor device available. Consult Factory.
Shand & Jurs “Expanda-Seal” option is available on all pressure pallet assemblies. This feature significantly reduces leakage. The ballooning effect of the FEP diaphragm effectively seals the valve.
The “Expanda-Seal” feature ensures less than .5 SCFH of air at 95% of the set point.
