In wastewater treatment plants, the flow control of the channels is done with penstocks. These caps, which are manufactured in a rectangular shape, are usually designed according to the size of the channel. It is manufactured with manual flywheel or automatic actuator according to the driven shape. The thicknesses of frame and cover are manufactured by calculating according to water pressure.
It is used with the purpose of controlling flow and sealing in tank structures in wastewater treatment plants. The wall mounted penstock have a wide range of sizes and are designed according to the openness to be covered and the pressure to be exposed.
It is used with the purpose of controlling and adjusting water levels in the tank structures of wastewater treatment plants. The weir penstocks have a large size range and are designed according to the level to be adjusted.
It is used to temporarily shut down or isolate a channel in wastewater treatment plants or to control water levels. In the case, the slides are created with the logs sitting on top of each other. The flow in the channel is controlled by adding or removing the log.
