This valve is the in-line version of discharge valve submerged vertical sleeve type; by the particular flow path and the selected trim style, it can be utilized on the pipeline points where there is very high head loss requirement and extremely cavitation risks.
Nencini designs the valve and its shutter (standard or multijet) in front of the hardest system data.
The main data on this type of valve follows:
|
| Medium |
Water (drinking, corrosive, waste) |
| Features |
The valve is capable of dissipating an excess pressure head greater than 300 meters (1000 feet), without an cavitation problem.
Bubble tight shut-off. |
| Application |
In-line flow/pressure control; powerplant bypass; discharge purpose.
To achieve all the whatever system conditions many trim style are available;, standard, multijet single and double stage. |
| Size |
From DN100 to DN1800 (from 4" to 70") |
| Pressure Class |
From PN10 to PN100 (from ANSI125 to ANSI600) |
