Protectosea 7800系列緊急泄壓裝置被設計用于提供緊急救濟以外的經營提供發泄在TANK的能力。該系列號7800口不提供真空的泄壓。真空救濟必須由獨立經營的通風口（見Protectoseal系列第830號8540H系列，6240系列號，系列號18540或系列號16240）。
在正常工作條件下，發泄托盤大會提供了一個有效的封閉氣體密封。在發生緊急情況（消防水箱的參與）的情況下，托盤升降機回應在坦克的蒸氣空間越來越大的壓力。蒸氣排出，從而保護了從危險的過度加壓艙。托盤裝配自動關閉，reseals當壓力降低。

EMERGENCY PRESSURE VENT
Series No. 7800
Protectoseal Series No. 7800 Emergency Pressure Vents are designed to provide emergency relief capacity beyond that furnished by the operating vent on tanks. The Series No. 7800 vents do not provide vacuum relief. Vacuum relief must be supplied by independent operating vents (See Protectoseal Series No. 830, Series No. 8540H, Series No. 6240, Series No. 18540 or Series No. 16240).
Under normal operating conditions, the vent pallet assembly is closed providing an effective vapor seal. In the event of an emergency (fire involvement of the tank), the pallet lifts in response to the increased pressure in the tank's vapor space. Vapor is expelled, thereby protecting the tank from dangerous over-pressurization. Pallet assembly automatically closes and reseals when the pressure is reduced.
