They are available in sizes from 200 mm x 200 mm to 3000 mm x 3000 mm.

Thanks to their self-adjusting seal, they leak very little water in both open and closed positions. The leakage level is better than the limits set by DIN 19569-4 (Class 5) and AWWA C561 standards.

Metusan also produces custom penstocks for larger sizes and more difficult conditions.

Metusan penstocks are used to control water flow in wastewater treatment plants, irrigation systems, hydroelectric power plants, and other hydraulic structures.
