Hydraulic Gates, Penstocks and Stoplogs

According to the project requirements Nencini engineers and produces several kinds of hydraulic gates:

• slide gates
• ring follower gates
• radial gates.

Penstocks and stoplogs are low pressure intake devices for channels, tanks and basins, and are usually wall-mounted. The normal position is the open one, they close when maintenance is required. To allow an easy handling, stoplogs are usually composed by several units that must be lift by a lifting beam and positioned one on top of the other to reach a level higher than the required water level.

Materials :

• body in structural steel (carbon or stainless steel)
• leaf (for gates) in structural steel (carbon 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 :

• hydraulic power plants (gates)
• low-pressure intakes in channels, tanks and
• basins (penstocks and stoplogs).
