ISO 7368:2016 pdf free download.Hydraulic fluid power – Two-port slip-in cartridge valves – Cavities.
1 Scope
ISO 7368 specifics only geometrical data relating to cavities in which two-port hydraulic slip-In cartridge valves are mounted in order to ensure interchangeability.
NorK For esample. ISO 7368 does not specify rated pressures.
It applIes to cavities [or two-port hydraulic slip-In cartridge valves which are generally applicable to
Industrial equipment.

3 Terms and deflnitions
For the purposes of ISO 7368, the terms and definitions given In ISO 5598 apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
5) Z1: supplementary pilot, inlet:
6) Zi: supplementary pilot, return;
b) F1 … F12 Identify threaded holes for fixing screws; r) 6, Gi and G2 identify the location of pin holes;
d) D Identifies the fixing screw diameter;
e) rmas identifies the mounting surface edge radius;
F) R indicates the maximum radius at the bottom oldj. The code system used in ISO 7368 is defined in ISO 5783. NOTE Size 15 and size 16 are not yet listed in ISO 5783
S Tolerances
The following requirements shall be applied to the sealing and chamfer surfaces. i.e. that area within the chain lines:
— surface roughness (see ISO 3601-2);
— surface roughness, Rz as indicated on the figures according to ISO 1302 and ISO 4287;
— all non-specified surface finishes: Ks 63;
— surface roughness values are given in micrometres (nm);
— surface flatness: 0.01 mm over a distance of 100mm (see ISO 3601-2).
The following tolerances shall be complied with along the x,y and z axes with respect to the origin:
— pin holes ±0,2 mm;
— screw holes: ±0,2 mm;
— port holes: ±0,2 mm:
— general tolerances according to ISO 2768-1 for linear and angular dimensions without tolerances.
