Orbinox SA Model Penstock Valve


Three-side sealing flush bottom multiple log aluminum stop log penstock with no actuator for open channels

The Orbinox model SA Aluminum Stop Log is designed for open channel installations for temporary isolation and flow control. Stop Logs are ideal for maintenance and repair works or flood control and diversion. The logs are made of extruded aluminum and are very easy to handle due to their lightweight.

The logs are stacked on top of each other in the frame guides. The water level is controlled by adding or removing logs. The sealing system is bidirectional (suitable for flows in either direction) and allows to achieve very low leakage rates.

The frame can be made of aluminum or stainless steel and it can be designed to be embedded in concrete, wall mount, or face mounted in an existing channel.
