Penstocks

Penstock

Laminar wall penstocks can be used as shutoff and control penstock. Square or rectangular in a compact design. Resilient seated with four-side sealing, constructed of stainless steel, for wall mounting.

Penstocks are mainly used as shutoff valves for water treatment channels, power stations, dams, etc. Laminar can offer penstocks  with a square, rectangular or round port.

The basic design consists of a steel frame, a sliding steel gate, a sealing system sliding inside the frame, a stem, and the actuation system. Standard models are manufactured in steel or stainless steel, providing a high corrosion resistance suitable for a wide range of applications.

Laminar offers penstocks that can be fitted into walls (to close circular, square or rectangular ports) or into channels (with frame enclosed in the concrete).
