Sigma Flow
Flood Control Unit
Flood control consists of either providing the ability to remove excess water from flood-prone areas during storm events or providing adequate storage space for excess water during periods of heavy rain. The first approach uses large pumping stations to evacuate extra water. The second approach uses canals, large water mains and other approaches to keep water contained until it can be naturally released. As water rises in these structures, many discharge lines that are normally well above the water level may suddenly find themselves deeply submerged. It is important, therefore, to protect all discharge lines in a flood control basin with reliable backflow prevention.
At Sigma Flow, we specialize in providing reliable isolation valves, including gate valves and butterfly valves, designed to minimize service disruptions during maintenance and repair. These valves are strategically placed to ensure that sections of the network can be isolated with minimal inconvenience to other service areas.

Control Valves
Control valves are integral to managing flow and pressure within the distribution system.
They are sized based on the desired flow rates, upstream and downstream pressure differentials, and flow velocities. SIGMAFLOW offers a variety of control valves, including pressure-reducing, pressure-sustaining, pressure-relief, flow-control, throttling, and float valves.
For maintaining optimal flow
Additionally, air release valves, essential for maintaining optimal flow, are installed at high points or gradient changes in the main pipeline. SIGMAFLOW provides a comprehensive range of air valves specifically designed for distribution lines.
Critical Valve Applications in Flood Prevention and Management
Valves play a crucial role in flood control by regulating water flow, preventing backflow, and managing pressure to protect vulnerable areas. Their proper use ensures effective flood prevention and the safety of infrastructure during heavy rainfall or storms.
- 1. Water Flow Regulation: Gate and Ball Valves control water flow through channels, reservoirs, and drainage systems, helping to manage flood risks in vulnerable areas.
- 2. Backflow Prevention: Check Valves, Anti-Backflow Valves, and Non-Return Valves ensure water flows in one direction, preventing backflow that could lead to flooding or contamination.
- 3. Pressure Management: Pressure Relief Valves release excess pressure from pipes or reservoirs to prevent system damage during high-water events.
- 4.Water Level Control: Float Valves automatically adjust water levels in tanks or reservoirs, preventing overflow by opening or closing as needed.
- 5. Floodgate and Sluice Control: Flood Control Valves and Sluice Valves manage the release of water from dams and floodgates, ensuring safe levels during storms or heavy rainfall.
