Abstract
A GLV-gas lift valve that uses dual 'Fortress™' seals on both sides of the bellowto protect said bellow from both high dome pressureacting against outside bellow surface and high injection pressure acting against bellowinternal surface. When valve is in closed position, after dome pressureis applied, upper-dome side 'Fortress™' seal is engaged and prevents high dome pressure reaching said bellowexternal surface. When valve is in fully open position, when injection pressureis applied, lower sealis engaged and prevents access of high injection pressure into bellow acting against bellow internal surface. This principle allows much higher pressures to be applied in valve dome section and injection section by reducing differential pressure across the bellow. In addition, lower “Fortress™” seal allows very high injection pressuremore than 10 KSI to be applied without damage to bellow or gas lift valve components.
