| Features of Calzoni' s Fixed Cone Valves |
|
• Accuracy of machinings
• High siffness of structural parts
• Special constructive solutions
This allow to have no leakages, no vibrations and easy maintenance.
|
| Operational characteristics:
The cylindrical shutter slides on the body, actuated by the control mechanism, thus adjusting the discharge opening.
Valve operation is by hydraulic, electromechanical, manual control.
Water dissipation is assured by the hollow jet which is originated by the particular shape of the body end.
