DIMENSIONS LIST(UNIT:MM):

Note:

1. Reduce bore ball valve have the same fact to face and end to end dimension as full bore ball valve of the same pipe size(indicated by first of the double digits, while the second is the reduced bore size).

2. Valve size is as same as nominal pipe size.

3. Dimension (C) of a welding X flanged end valves is once half the sum of dimensions (C) of a welding end and a flanged end valve of the same size and pressure rating.

4. Dimension and tolerances for flanges conform to ANSI B16.5 or MSS SP-44.

5. Welding ends conform to the drawing in Fig.434.8.3 A and Fig.923-B in ANSI B31.8.It is up to the purchaser to specify welding end.

6. "*" Factory Standards

7. We hereby reserve the rights of any alternative dimension that would help to improve our valve's quality and working efficiency
