- Foundry marking on the body : DN100 PN16
- Foundry marking on the cap:
- SG PAM logo
- Arrow indicating the opening direction
- Number of turns necessary to obtain a complete opening
- On an aluminium plate stuck on the cap:
- Commercial reference
- The year of manufacture
- On a label stuck on the body: the good position of the pipe in order to guarantee the position of KEYSER outlet and thus the correct assembly with the material of the firemen (bends).

- Outlet Type Keyser 4’’
- Flanges ISO PN10/16
- Maximum allowable pressure (PFA):
- Factory test pressure: body: 25 bars, shutter: 17,6 bars
Hydraulic characteristics
The system of obturator is especially designed so that the flow is established in a progressive way with the opening, thus avoiding the risks of water hammer.
Independent surface box without maintenance
The system of opening of the surface box (patented): the complete absence of hinge allows many openings and closings of the surface box without particular maintenance.
The strains on the surface box which is completely independent are entirely absorbed by the ground and not by the hydrant. The sealing of the junction with the water pipeline is kept.
The surface box is in conformity with the European Standard EN 124. Class C 250 (load 250 kN)
