Gate Seal

Dams and barrages are built for storage / diversion of water for irrigation or generation of electric power. In concrete dams, tunnels / spillways, head regulator of hydel channels, fore bay intake structure, by-pass channels and draft tube of power house, the flow of water is controlled with the help of hydraulic gates. To prevent flow of water past a closed gate, seals are provided either on the gate or on the metal frame in the gate slot. Rubber is the most commonly used material for seals, as it is elastic, deforms readily and regains its original shape on removal of load.
