Wastewater treatment penstock

cast iron

Evotech manufacturing wall penstocks, weir, and stop logs Penstocks re mostly used to block and control the water flow, and water level in rivers, channels, intake structures and water reclamation, but they are widely used also in WWT Plant, where treatment and cleaning of water are proceed. All the EVOTECH products are made by stainless steel AISI304 and/or AISI316, with special care at the choice of the raw material, as much as at the surface finishing quality. EVOTECH produces penstocks both on catalogue and on customer request with internal project, and even for big dimensions and high hydraulic load. Every product is designed and dimensioned with attention. All the penstocks are in accordance with DIN 19569 / BS 7775 / EN12266 Wall Penstocks / Sluice Gate The penstocks are installed in channels or above a pipes in order to intercept the water flow. The closed position is achieved when the slide reach the lower position. The opening is obtained lifting up the slide from the lower position. The flowing area is delimitated by the lower side of the slide and the bottom of the pipe or of the channel. The most common constructive solutions can be the insertion across a channel, or plugged on a wall, usually this last solution is suitable for pressure water flow. The frame can be as a gate, or with independent operating column, they can be manually activated or by an electrical actuator. In order to limit the torque required for the open/close operations, a geared reducer can be applied.
