Protectosea 7800系列紧急泄压装置被设计用于提供紧急救济以外的经营提供发泄在TANK的能力。该系列号7800口不提供真空的泄压。真空救济必须由独立经营的通风口（见Protectoseal系列第830号8540H系列，6240系列号，系列号18540或系列号16240）。
在正常工作条件下，发泄托盘大会提供了一个有效的封闭气体密封。在发生紧急情况（消防水箱的参与）的情况下，托盘升降机回应在坦克的蒸气空间越来越大的压力。蒸气排出，从而保护了从危险的过度加压舱。托盘装配自动关闭，reseals当压力降低。

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.
