HYDRAULIC EQUIPMENTS
HYDRAULIC EQUIPMENTS
This document provides comprehensive information on hydraulic equipment used in water management, focusing on flow controllers, penstocks, and flap valves. These devices are crucial for regulating wastewater and rainwater in infrastructures such as storm basins, overflow holes, and sewage treatment plants.
- Operating Principles: Flow controllers maintain a constant outflow regardless of upstream water levels, utilizing principles like the hydraulic vortex effect and surface water intake.
- Product Ranges: Includes HydroRégul, HydroVortex, HydroDB, and HydroSurf, each designed for specific flow rates and water heights.
- Model Selection and Installation: Criteria include wastewater type, flow rate, water height, and installation type, with options for open-air or chamber installations.
- Service and Manufacture: Custom-made penstocks available in various configurations, including motorized options and those with PEHD disks.
- Configurations: Designed to suit specific installation needs, with options for manual control and motorization.
- Hydroclap Range: Designed to prevent backflow, available for wall mounting or installation on PVC pipes.
- Flow controllers are recommended for light wastewater and rainwater, with specific models not suitable for heavy wastewater.
- Installation requires precise alignment and fastening for optimal performance.
- Regulation precision is critical, with some models offering adjustments within a 5% margin.
- Flow controllers are constructed from 316L stainless steel, ensuring durability and corrosion resistance.
- Penstocks are made from hot galvanized steel or 304L stainless steel, featuring full-flow round orifices and removable EPDM seals.
- Flap valves are made of polyester with EPDM seals and 304L stainless steel bolts.
- Installation requires smooth, vertical concrete walls for wall-mounted devices or horizontal pipes for mounted devices.
- Maintenance involves ensuring proper sealing and adjusting components as needed.
- Materials comply with NF A 91121 standards for hot galvanized steel.
- Pressure resistance for flap valves is 0.5 bar (5 m water head).
- Weights for galvanized and stainless steel penstocks range from 9.1 kg to 48.4 kg depending on size.
- Flap valve dimensions and weights vary by diameter, with Dn 315 weighing 5.2 kg and Dn 500 weighing 9.6 kg for wall-mounted devices.
The document provides detailed guidance on selecting and installing hydraulic equipment for effective water management, emphasizing the importance of choosing the right model based on specific operational requirements.

The water intake at the surface allows highly precise regulation (+ or – 5%) (see curve to the right). It can regulate flow rates from 5 to 170 l/s for a maximum water height of 2 m and it can be installed on outlets with a cross-section from 100 to 350 mm. It is very suitable for installation in a basin before...
