Indian Standard

DIMENSIONS FOR FERROUS VALVES - FACE-TO-FACE AND END-TO-END

‘1. Scope- Covers face-to-face and centre-to-face dimensions of flanged valves, as well as end-to- end and centre-to-end dimensions of butt welding~end valves, to permit a degree of dimensional interchangeability.

2. Pressure Rating -The range of pressure rating is Class 125 - 150- 250 -3OO- 600 - 900 - 1500 and 2500.

3. Nominal Size- The range of nominal size in DN values is IO - 15 - 20 - 25 - 32* - 40 - 56 -65*-80-tOO-125- 150-200-250 -3OO-35O-4OO-45O-5OO-6OO-7OO-6OO-9OO - 1000.

4. Terminology

4.1 Face-to-Face Dimensions ( for Straight Pattern Valves ) -The distance, expressed in millimetres, between the two planes perpendicular to the valve axis located at the extremities of the body end ports as specified in Tables 1 to 4.

4.2 Centre-to-Face Dimensions ( for Angle Pattern Valves ) - The distance expressed in millimetres, between the plane located at the extremity of either body end port and perpendicular to its axis and the other body end port axis.

4.3 @d-to-End Dimensions (for Straight Pattern Valves) - The distance, expressed in millimetres, between the two planes perpendicular to the valve axis located at the root faces of the welding,lips.

4.4 Centre-to-End Dimensions ( for Angle Pattern Valves ) - The distance, expressed in millimetres, between the plane located at the root faces and perpendicular to its axis and the other body end port axis.,

5. Standard Facings

5.1 The face-to-face dimensions given in the tables are for valves having the standard facings as indicated below:

a) Plain flat face - Cl.125 cast iron valves.

b) I.6 mm raised face- Cl.250 cast iron valves, Cl.150, Cl, 300 steel valves.

c) 6’4 mm raised face - Cl.600, Cl.900, Cl.1500, Cl.2500 steel valves.

Face-to-face dimensions given in tables are inclusive of the raised face thicknesses,

6. Special Facings -When special facings *are required reference shall be made to Indian Standard ‘ Steel pipe flange and flanged fittings ( under preparation) ‘. Details of additional requirements in respect of ring joint end flanges are given in Appendix A to obtain new face-to-face dimensions for valves with such a joint.

7. Dimensions and Tolerances - The face-to-face or centre-to-face and end-to-end or centre-to-end, as appropriate, for the valves included in this Indian Standard shall be In accordance with Tables 1 to 5 and tolerances shall be in accordance with Table 6.

*Non-preferred sizes.
