Vertical Quick Opening Manway for Pressure Vessels and Filter Separators. Tool-Less Design.

The TOOL-LESS® closure satisfies the design requirements of ASME B31.3, B31.4, B31.8, and Section VIII, Div. 1. The entire design has been verified through proven stress calculations, the latest finite element analysis software, and strain gauge testing, establishing a high level of confidence in the structural integrity of the TOOL-LESS® closure. In addition, fatigue analysis based on severe field condition data has been successfully conducted on all closure sizes and classes. TOOL-LESS® closures are available in Carbon Steel, Stainless Steel, and other alloys, along with a choice of elastomer lip seal materials to meet the user’s temperature and process compatibility requirements. quick opening closures is customizable to specific design codes, pressure ratings, material requirements, and installation conditions. Best used for: pig traps, filters, strainers, scrubbers, heat exchangers, blowdowns, and other vessels
