6 INSTALLATION

6.1 Preparation for installation

The dimensions of the NeoSeal valve have been 
chosen so that, in the case of a wafer body, 
it can be clamped between all current DIN, 
ANSI and JIS flanges of the appropriate size.
Principal dimensions of the valves: refer to 
the catalog page for data.
The flanges must meet the following 
requirements (see table below).

• Cleaned and undamaged mating surface.
• The internal diameter of the mating flange 

must have the following dimensions:

  Minimum: Y-dimension of the valve plus 

sufficient clearance for the valve disc.

  Maximum: if the flanges have a raised face, 

the outside diameter of the raised face 
must not be less than dimension ‘R’ of the 
butterfly valve.

• The appropriate flange bolt hole 

arrangements in the various flange standards 
and diameters allow the valve to be centered 
by passing the flange bolts through the 
holes in the mounting plate of the valve.

• The flange bolts must be centrally aligned 

in the holes in the valve mounting plate.
