Marking
On body:
- Nominal diameter in mm (DN),
- Nominal pressure in bar (PN).
On identification label:
- Reference of valve
- Closing direction (FSH / FAH)-nominal diameter (DN)-flange drilling
- Year and month of manufacture-number,
- Number of the norm
A label certifies the conformity of EURO 20 with flanges to the quality norm.
The letter T indicates that the gate-valve has satisfied the hydraulic tests made at the end of the manufacture process.
