Tainter radial penstocks
Tainter radial penstocks are used to control and regulate flows, typically water, in hydroelectric dams, canals and spillways.
This type of penstock consists of a gate with a structure in the form of rotating arms and a drive system.
Structure
The gate is characterised by a curved shape, with a square or rectangular cross-section, which allows the hydraulic force to be transmitted efficiently. Rubber sealing gaskets are integrated into the electro-welded structure to seal against the metal profiles installed in the civil works.
Effectiveness
In Tainter radial penstocks, the sealing can be located on four or three sides, depending on whether or not the water level exceeds the height of the gate. The rotating arm structure efficiently transmits hydraulic force radially to the pivoting plates installed in the civil works.

Technical data
Materials
Coutex Sorigué’s Tainter radial penstocks can be designed for any size and water load, using a variety of materials such as carbon steel or stainless steel (typically AISI 304L and 316L), among others.
Made-to-measure design
The design of the radial penstock and its drive system are adapted to the specific needs of each project, taking into account the dimensions of the hydraulic structure and the volume of water to be regulated.
Dimensions
The following data are necessary for calculating the dimensions of the penstock:
Width of the canal or recess
Maximum water level, measured from the base of the penstock
Canal height
3 or 4-sided sealing
Drive type
Drive
A Tainter radial penstock can be driven using electric, oil-hydraulic or other means.
