Abstract (en)
A dual-containment isolation valve to minimize leakage through a valve coupled to a fluid storage container. The isolation valve of the invention includes a flange for mating to an upper surface of the container, with a sealing gasket inserted therebetween. As the valve's standard male threads are threaded into the container's standard female threads, the valve's flange is drawn toward the container's upper surface. The coupling of the valve to the container results in a sealing compression of the gasket between the flange and the top surface. The container's top surface is preferably machined to a flat finish to increase gasket-to-surface contact. The valve optionally includes a pressure indicator port for coupling the valve to a pressure indicator. <IMAGE>
