Bolt lengths may vary due to manufacturing tolerances in valves, gaskets, flange bolts and flanges. NOTE: The FNW figure HP high performance butterfly valves are designed to fit between ANSI B16.5 class 150 flanges. Lengths are based on the minimum flange thickness of weld neck flanges per ANSI B16.5 and use of standard 1/16” gaskets.

Butterfly Valve Bolt Chart provides detailed information on bolt sizes, types and materials for different valve sizes and applications.

Studs & Bolts for Mounting Butterfly Valves 2” to 24” Between ANSI Class 125/150 Flanges

2024年4月15日 · First, consult the butterfly valve bolt chart to figure the suitable bolt size and length for the valve and flange that you have. Chart will give information on the recommended bolt diameter corresponding to the valve size, pressure rating, and flange type.

Bolt lengths may vary due to manufacturing tolerances in valves, gaskets, flange bolts, and flanges. ZSPEC resilient seated butterfly valves are designed to fit between ANSI B16.5 class 150 flanges without flange gaskets.

Bolting lengths are calculated based on ASME B16.5 Class 150 RF flanges. For 4” and larger ASME B16.1 Class 125# flanges, use bolt lengths above. Consult factory for 3” and smaller valves when using ASME B16.1 flanges. Bolting lengths do not include clearance for washers.

2024年6月27日 · To determine the appropriate bolt size and length for your valve and flange, first refer to the butterfly valve bolt chart. The recommended bolt diameter for each valve size, pressure rating, and flange type will be shown on the chart.

FLANGE BOLTING GUIDE FOR FIGURE 7xx-SERIES BUTTERFLY VALVES WARNING: Improper bolt and stud lengths could result in leakage at the flange resulting in damage, serious injury, or death. CAUTION: Dimensions provided for flange bolting are intended only as a guide.

butterfly valve bolt chart is a graphical representation of the different types of bolts that can be used with a specific type of lug butterfly valve. The chart shows the size and weight of the bolts, as well as the compatibility of each bolt for use in various applications.
