Hole Pattern of Mounting Surface
The mounting manifold must conform to
ISO 4401-08-08-0-05.
• For a maximum flow rate, the ports P, T, A and B should
be provided with a diameter of 32 mm (1.26 in) (not
according to standard).
• Flatness of mounting surface < 0.01 mm (0.0004 in)
over a distance of 100 mm (3.94 in).
• Mean roughness R
a
better than 0.8 µm (0.0000314 in).
