Penstock, sluice gate, water gate
are 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 wastewater treatment plants, where treatment and cleaning of water are proceed.
All the penstocks, sluice gate and water gate of manufacturing SEFT are made by stainless steel AISI 304L or AISI 316L with special care at the choice of the raw material, as much as at the surface finishing quality. SEFT manufacure 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 and sluice gate are in accordance with DIN 19569 / BS 7775 / EN12266
The penstocks and Sluice Gate are installed in natural or artificial 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 delimited 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.
