(End of line, weight loaded, integrated, atmospheric deflagration proof)

Storagetech™’s Model 102 Pressure-Vacuum Relief Valve with Integrated End-of-line Flame Arrestor provides total security of mind to operators of storage tanks. The Model 102 ensures protection against damage through over-pressurisation, implosion due to vacuum conditions, and prevents any external flame entering the tank.

In the closed position the pressure relief pallet and diaphragm assembly is held tightly against a seal to prevent the loss of vapour to atmosphere. As the internal pressure in the tank increases, due to product filling and vapour development, the pressure in tank increases and in the event that the set pressure of the unit is reached, the diaphragm will open and discharge the gas to atmosphere. The opening set-point is selectable from a range between 1 and 28.1 W.C. (2.5 and 70 mbar), and the valve will reseal when the tank returns to a safe pressure.

ISO 16852:2008 – Flame Arrestors, Performance requirements, test methods and limits of use.

API RP 2210 -Flame Arrestors for Vents of Tanks Storing Petroleum Product.

The size of the vent should be calculated in accordance with API Standard 2000 (ISO 28300) – Venting Atmospheric and Low-Pressure Storage Tanks or other international standards.

The integrity of the seal is tested for leakage in accordance with API Standard 2521 – Use of Pressure-Vacuum Vent Valves for Atmospheric Loss.
