AVK offers the two most common types of penstocks, wall and channel penstocks. They come in sizes ranging from 150×150 up to 2000×2000, with a rising or non-rising stem, as well as different mounting configurations and material combinations. There are also many different types of extensions and actuators to accentuate the penstocks.
