- Penstocks and Stoplogs
Penstock and stoplogs are low pressure intake devices for canals, reservoirs and basins and are usually wall mounted.
Normally in the open position, they are closed in the event of maintenance. To allow for easy handling, stoplogs are usually composed of several units that must be lifted by a lifting beam and positioned one above the other to reach a level above the required water level. Thanks to its manufacturing experience, Nencini offers Penstocks and Stoplogs in different materials:
- body made of structural steel (carbon steel or stainless steel)
- sliding guides in stainless steel, bronze or special alloy
Tightness system : metal on metal or by soft seal (EPDM, NBR, Teflon, etc.).

Applications
The engineering know-how, the high-quality production and the custom installation on site, makes this kind of product suitable for low-pressure intakes in channels, tanks and basins.
