Due to the high request for automatisms in drinkable water net distribution, careful to technical and technological innovations our company is proud to present a system for the discharge of aqueducts' terminals.

The system allows automated and timed discharges of aqueduct lengths;
This operation is usually made manually, to avoid back water deposit or sediments in case of users low drawings (for example during night hours, etc..).

In the control panel we have a timer that offers the possibility of weekly or daily programming of the time length of opening of the valve.

System's advantages:

- great autonomy battery supply.
- no need of connection to electric network.
- high reliability.
- components high quality.
- economical fast and easy installation.
- low maintenance.
- wide range from 2” to 8”.
- technical assistance.
- options: battery recharging solar panels.

Diaphragm hydraulic check valve

International pat. Bermad series 400.
The series 400 valves have been developed for the control of all kinds of aqueducts and industrial systems.
These kinds of valves combine simple and trustable realization with high performances, being virtually free from the usual limitations of this kind of components.
