ISO 6263 pdf download Hydraulic fluid power — Compensated flow-control valves — Mounting surfaces
Scope
This International Standard specifies the dimensions and other data relating to surfaces on whichhydraulic compensated flow-control valves are mounted in order to ensure interchangeability.
lt applies to mounting surfaces for hydraulic compensated flow-control valves which represent currentpractice; they are generally applicable to industrial equipment.

4.3 The code system used in this International Standard is defined in ISO 5783.
5 Tolerances
5.1 The following requirements shall be applied to the mounting surface, i.e. that area within the chain thick lines:
surface roughness: see ISO 3601-2:2008, 5.1.4 and 5.2.3;
surface flatness: 0,01 mm over a distance of 100 mm (see ISO 3601-2:2008, 5.1.4);
tolerance for diameters of locating pin holes: H12.
5.2 With respect to the origin, the following tolerances shall be complied with along x and y axes:
pin holes: ± 0,1 mm;
screw holes: ± 0,1 mm;
port holes: ± 0,2 mm.
For other dimensions, see the figures.
6 Dimensions
6.1 Mounting surface dimensions for hydraulic compensated flow-control valves shall be selected from the figures and tables specified in 6.2 to 6.9.
6.2 Mounting surface dimensions for compensated flow-control valves with main ports of 4,5 mm maximum port diameter (code: 6263-02-01-*-13) are given in Figure 1 and Table 1.
6.3 Mounting surface dimensions for compensated flow-control valves with main ports of 7,5 mm maximum port diameter (code: 6263-03-02-*-13) are given in Figure 2 and Table 3.
