The valve that does not meet the corresponding requirements of ASME/ANSI B16.42 or ANSI/AWWWA C504 should be determined by the minimum wall thickness. This minimum wall thickness is determined by the use of design and using these standards. Essence

The replacement method does not meet the valve of the corresponding requirements determined by ASME/ANSI B16.42 or ANSI/AWWA C504 corresponding requirements. The reduced valve wall thickness between the valve body and the adjacent bolt hole of the valve body should not be less than 25%of the wall thickness required by the neck of the valve body.

 For the vessel valve coected to the flange coection, if the materials listed in the French standards in Section 2 are not used, the minimum flange thickness should be used to determine Essence For the consideration of flange, minimum flange thickness should never be less than the values listed in the standard.

Pressure rated value is designed for its truncated pressure rated value or pressure difference than the valve body pressure rated value, and the valve can be designed. This pressure rated value shall be marked in accordance with the provisions of Section 12 of this standard. The flange level that does not list in the Versey Frank standard exceeds the scope of this standard.

The flange bolt 5.4 The flange bolt hole of the valve body is the cast iron, the ball ink cast iron, and the non -ferrous metal ship's valve. There should be a bolt hole of the 2B -level drilling hole and the attack wire according to the ASME B1.1 coarse dental threaded series. All -level steel valves for the screw holes are scheduled to use the screw holes. For the bolt with a specification of 1 inch less than the same as the specifications of the ASME B1.1 thick tooth series 2B drilling and attack wire; 1 '/A -inch bolt is based on the 8 -tooth series 2B drilling and attack wire.
