Standards this line is built to
The designations below are cited by the products on this page. A specification is written in these, not in product names, so each one is set out with what it governs. Progress Horizon Trading supplies this line as an authorized distributor across Saudi Arabia.
EN 12266-1
Pressure testing of metallic valves: the shell and seat tests a valve passes before it leaves the factory.
EN 1092-2
The cast-iron counterpart to EN 1092-1, for flanges on cast-iron valves and fittings.
EN 558
Face-to-face and centre-to-face lengths for valves in pipeline systems: the dimension that decides whether a replacement valve fits the existing gap.
VDI 2073
German guidance on hydraulic circuits in heating and cooling systems: the basis for how a hydronic network is balanced.
NSF/ANSI 61 Annex G
The lead-content limit within the drinking water standard: the basis of the 'lead-free' designation for potable water components.
PN 16 / PN 25
Available in nominal pressure ratings of 16 and 25 bar, which sets both the flange drilling and the rated body pressure.
EN 60534-2-3
Test procedures for control valve flow capacity: how the Kv figure a designer sizes on is actually measured.
PN 16
A nominal pressure rating of 16 bar. The PN figure sets the flange drilling and the pressure the body is rated for.

IEC 60534-8-3
Predicting the aerodynamic noise a control valve will generate, so the acoustic consequence can be calculated at design stage rather than discovered on site.
