Stainless steel penstocks and flap valves

For over 35 years, TESACO has been developing and manufacturing penstocks, flap valves, and special solutions for water and wastewater technology. Our products are used in sewage treatment plants, pumping stations, stormwater overflow basins, stormwater retention basins, and other hydraulic engineering structures.

Our solutions

Penstocks and control penstocks

Our penstocks and control penstocks precisely control and shut off media in hydraulic structures. Penstocks guarantee secure shut-off, while control penstocks limit flow permanently, accurately, and reproducibly thanks to a special slide rail.

Cast iron and stainless steel flap valves

Our flap valves reliably protect structures and pipelines against backflow. Various cover versions as well as project-specific designs allow for optimal adaptation to the respective installation situation.

Stainless steel channel penstocks

Our channel penstocks reliably protect and regulate open channels, conduits, and hydraulic structures through a three-sided seal. Various operating methods and installation types, as well as project-specific designs, allow for optimal adaptation to the respective installation situation.

Digital planning tools

Plan faster and more securely with our digital tools. Configure penstocks and flap valves, calculate flow rates, and access planning drawings, CAD data, installation dimensions, and technical documentation directly.
