a For flange types F05 to F30,other dimensions of d₇between those indicated are permitted.
b For flange types above F30,the given dr values correspond to the maximum and any value up to this maximum is permitted,subject to considerations in footnote d.
c Indicates the preferred dimension
d For flange types F05 to F30,these values are the corresponding torques which can be transmitted by the driving components having the d₇dimensions.They are based on a maximum allowable torsional stress of 280 MPa for the driven component.
e The maximum transmissible torques shall be determined by calculation fh₄min=0,5 mm
g dz shall be manufactured within the diameter tolerance H9
ISO 5211 specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.
The attachment of part-turn actuators to control valves in accordance with the requirements of this document is subject to an agreement between the supplier and the purchaser.
ISO 5211 specifies:
— flange dimensions necessary for the attachment of part-turn actuators to industrial valves [see Figures 1 a) and 1 c)] or to intermediate supports [see Figures 1 b) and 1 d)];
— driving component dimensions of part-turn actuators necessary to attach them to the driven components;
— reference values for torques for interfaces and for couplings having the dimensions specified in this document.
The attachment of the intermediate support to the valve is out of the scope of this document.
