This automatic operated valve, double flanged type, is used on pipeline.
Nencini can perform two different types of automatic control transmitted from the floater to the valve:
1)_ mechanical joint by lever mechanism to the valve shutter; it means gradual closing/opening operations by changing water level and it required a valve site close to the floater.
2)_ hydraulic connection by secondary pipe to the valve element; the valve works as on/off type in front of
the maximum water level but you can place the valve far from the floater.
The main data on this type of valve follows:
|
| Medium |
Water (drinking, corrosive, waste) |
| Features |
Unrestricted or restricted flow path; double or single disc type; anti-cavitation trim if required
from system data; bubble tight shut-off.
|
| Application |
On the inlets to the service reservoirs, tanks or canal, with or without stilling chamber for floater
|
| Size |
From DN50 to DN1600 (from 2" to 60") |
| Pressure Class |
From PN10 to PN100 (from ANSI125 to ANSI600) |
