EGC Engineers offer a wide variety of Live-Loaded packing set configurations. Live-Loaded packing sets are used to prevent loss of gland force caused by thermal cycling, pressure surges, packing relaxation, wear or extrusion. In these cases, EGC engineers a packing set consisting of Belleville springs and EGC valve stem packing. The combination improves performance by delivering the right gland force over a longer period. Applications are typically found in refineries, petro-chem, power plants, and pulp and paper.
