Apollo Ball Valves (Top Entry - Fugitive Emission Bonnet Dimensions)

Features:

Two types of Fugitive Emissions Bonnets are available. The first type intended for manual operation and is equipped with high performance stem packing. Testing has shown that live loading this high performance packing is the best choice for high cycle applications. The live loaded type is not only more appropriate for unattended automated operations and high cycle applications, it is also well suited for applications involving thermal cycling.
The two styles of packings available for the Fugitive Emissions bonnet are a double stack of RPTFE Chevrons or the special graphite EVSP 9000 style packings.
The lower, primary packing stack is pressure activated as well as statically loaded by the jack nut. The upper packing stack acts as back-up seals in the case of primary seal failure. A purge port is available between the two packing stacks for the purpose of detecting primary seal leakage.
One of the most valuable features of the Fugitive Emissions Bonnet is that it can be added as an upgrade at a later date to existing installations. In addition to being able to order Top Entry valves with any of three bonnet styles direct from the factory, kits are available that are pre-assembled with the stem, bonnet, packings, glands and jam nut installed and properly torqued for dependable performance. In a case where the service or regulations change and a design upgrade is required, the Top Entry Ball valve is designed to accommodate these changes. Contact the factory for kit part numbers for any specific valve or application.

Materials of Construction:

Extended bonnets are available in the same materials of construction as those illustrated on page K5 for the bonnet, stem, stem packings, packing gland, nuts and body seals.
