Structure & Working Principle
1. Core Components
The flanged foot valve includes a valve body, valve disc, valve cover, bushing, sealing ring, and flanged ends. Fluid pressure opens the disc to allow inflow, while backflow pressure instantly closes the disc when the pump stops, ensuring unidirectional flow.
2. Design Features
- Robust Flanged Connection: Designed with ANSI/EN-standard flanges for secure, leak-proof installation in high-pressure or large-diameter pipelines.
- Anti-Clogging Optimization: Reinforced ribs and multi-port inlet design reduce clogging risks in media with suspended particles.
-Corrosion Resistance: Stainless steel construction (304/316/316L) ensures durability in harsh environments.
Applications
- Industrial Pump Systems: Installed at suction pipe ends to maintain prime and prevent pump cavitation.
- Large-Scale Water Treatment: Ideal for vertical or horizontal pipelines in wastewater plants, cooling systems, or firefighting networks.
- Chemical & Oil Industries: Resists corrosion in acidic/alkaline media; suitable for refineries and chemical transport.
Installation & Maintenance
1.Installation Guidelines
- Ensure flange alignment with gaskets and bolts torqued evenly to prevent leaks.
- Install vertically with sufficient submersion depth to avoid air entrapment.
- Pre-prime the suction line before startup for optimal vacuum efficiency.
2. Maintenance Tips
- Inspect flange gaskets and bolt tightness periodically.
- Clean internal components during shutdowns to remove sediment buildup.
- Replace worn seals using manufacturer-approved kits to maintain integrity.
