EVR Multi -Port Thread -On Spill containers are available in Composite or Cast Iron bases with either 5 or 7.5 gallon buckets. Drain Valve Spill Bucket & Plug Spill Bucket standard on Dual Ports, Drain Valve Spill Bucket standard on Single Port. • Required for EVR APPLICATIONS - The FSA -400 Threaded Riser Face Seal Adaptor is installed on the fill pipe below the spill container to provide a true sealing for the drop tube flange on the 61 SO-EVR overfill prevention valve. The 61 SO-EVR series valve is installed in the base of the OPW EVR spill container with the patent pending 61JSK jack screw device. This configuration allows liquid in the spill container to be drained directly into the drop tube, thereby isolating the drain valve from the tank ullage, eliminating a notorious leak point in previous systems.
