4.1.5. Calculation of Wafer (WF) Type Bolts

“Wafer” type bolts pass through two flanges and a valve body. The calculation includes:

• Contribution of the nut (nut thickness × number of nuts)
• Contribution of the washer (washer thickness × number of washers)
• Contribution of the additional length
• Length of the valve body (from the valve's "Length" property)
• Stub end offsets on both sides (if applicable)
• Flange thicknesses for both sides
