Penstocks

Penstocks or shut-off fittings are used as control valves to control and regulate the flow of water and other liquids. Different application requirements call for expert advice. HAILO Professional offers various models of penstocks in its portfolio.

As a rule, penstocks are attached to the wall, in the case of round drainage shafts also with the aid of a segment stone. Regardless of whether the penstock is to be used to regulate water flows or for complete shut-off, HAILO Professional offers the right model for all requirements. Penstocks are suitable for use in manhole structures, sewers and open channel systems. Due to their low maintenance costs, penstocks are often used in municipal and industrial sewage treatment plants, for example.
