1. Thread engagement in accordance with ASME B31.3 "Chemical Plant and Petroleum Refinery Piping".
2. Bolting lengths are based on installation of valve between standard raised face flanges and utilizing flange gaskets with a final compression thickness of 0.125 inch. When gaskets used have
a final compression thickness of less than 0.125 inch, reduce bolting lengths shown by 0.25 inch.

1. See figure 4 for recommended valve orientation.
D For Wafer‐Style Valves: Install the lower flange bolts first to form a cradle for the valve (see figure 5). See table 5 for
flange bolt specifications.
D For Single‐Flange Valves: Position the valve between the flanges. Be sure to leave enough room for the flange
gaskets. Install the lower flange bolts.
2. For all Valves: Select the appropriate gaskets for the application. Flat sheet, spiral wound, or other gasket types,
made to the ASME B16.5 standard or user's standard, can be used on Control-Disk valves depending on the service
conditions of the application.
