Notes

Flange Size D, D1, D2, Z–ød, B, L values are based on standard flange dimensions for butterfly valves. Sketch in the size of code is only part of it.
For PN1.0MPa, Z = 8 according to JB78/82 standard; for other pressures Z = 4.

* Flange size D, D1, D2, Z–ød, B, L values are connected with a standard butterfly valve flange size. Sketch in the size of code is only part of it.
