Example of valve body nomenclature for shut-off valves:
PS55|DN32|S50|RX|35|2LA66 |
Maximum allowable pressure in bar |
PS55|DN32|S50|RX|35|2LA66 |
Nominal diameter |
PS55|DN32|S50|RX|35|2LA66 |
Material |
PS55|DN32|S50|RX|35|2LA66 |
Size of valve body (only for steel valves) |
PS55|DN32|S50|RX|35|2LA66 |
Maintenance connections (position and quantity), Exemplary designations are |

Nominal diameters (DN) are not actual dimensions!
The nominal diameters DN10 .. DN200 only indicate ranges! The number is not a quantifiable unit, it is only indirectly related to the diameters of the connections and should not be used in calculations.
