Flanges, flange dimensions and flange connections conform to ISO 7005 and EN 1092 respectively.
Valve types
2-port valves: VVF..
3-port valves: VXF..
Flange type
Type 21 (integral flange) as per ISO 7005 is an integral component of a pressure device.
Type of flange and flange face
Type B Type B1 The illustration shows the transition from the flange to the valve body of the V..F.. valves (not true to scale, faces only outlined) |
Type F (with recess) |
Gaskets
In the case of ISO 7005, the gaskets do not constitute part of the standard – in contrast to EN 1092.
Note
Up to DN 50, PN 25 is also used for PN 16
Up to DN 50, the flange dimensions of pressure classes PN 16 and PN 25 are identical. For this reason, for kvs values ≤ 40 m3/h and nominal sizes ≤ DN 50, the valves of the V..F53.. line (PN 25) are listed in place of the valves of the V..F43.. line (PN 16). |

Bypass-Port B
The valve series VXF22, VXF32, VXF42, VXF43 and VXF53 have a greater interior diameter in bypass port B versus the nominal value. This is not a problem when used with any standard ISO7005 and EN1092 steel flanges but ensure that any connection method used is explicitly designed for a specific interior diameter is compatible with this grater interior diameter..
