We have a range of HDPE (High Density Polyethylene), Aluminum and the “trendy” Composite Flap Gates. This range comprises of lightweight, corrosion resistant flap gates which act as Non-Return Gates and check gates for the prevention of reverse flows.
Flap gates are designed for use at the discharge point of water control systems. They prevent back flow or intrusion of tidal waters or storm waters back through the discharge structure. Flap Gates may be installed on all size discharge openings.
Typical applications include discharges to tidal waters, manholes, culverts, reservoirs, ponds basins and standpipes. Flap Gates permit the outflow of water while preventing back flow.
Screw down gates are commonly selected for water levels and flow rates controls in rivers and waterways. They are also used in raw water treatment plant, wastewater treatment plants and primarily for use of flow control of weir, irrigation, and flood control with minimal leakage.
Roller gates are designed to control water flow through large waterway / canal openings where cost-effective and ease of operation are important. A roller or fixed wheel gate consists of a fabricated steel slide with cast iron rollers and rubber seals. It varies in width and height as required by the size of the opening in the structure and varies in thickness depending on the depth of water. Recesses at the sides of the gate opening are provided with rails and with contact faces for side seal.
