Drawing on extensive experience in the pressure relief field, the BS&B FlameSaf®
Emergency Relief Vent offers a dependable, internationally certified and precisely
engineered design to prevent excessive pressure build-up and rupture of valuable
tankage during abnormal operation or as a result of exposure to fire. Designed for
the highest standards of precision and safety, these vents use fluoropolymer or
elastomer diaphragms to provide tight seals between pallet and seat, which coupled
with the 10% overpressure feature result in reliable and accurate response to even
minimal changes in pressure. Users benefit from optimized operating conditions
close to MAWP (Maximum Allowable Working Pressure) while ensuring operation
that safeguard both personnel and environment.
