Structure & Working Principle
1. Core Components
Crafted with precision, the foot valve comprises a robust valve body, dynamic valve disc, secure valve cover, durable bushing, and a reliable sealing ring. When fluid pressure engages the disc, the valve opens seamlessly, allowing an efficient liquid influx. Upon pump cessation, pressure from the outlet side closes the disc instantly, ensuring a secure backflow prevention.
2. Design Features
- Anti-Clogging Design: Engineered with multiple inlet ports and reinforced valve cover ribs, it minimizes blockage risks, even in media with minor impurities.
- Connection Types: Versatile connections support both threaded (screwed) and flanged options, catering to diverse pipeline needs.

Applications
- Pump Systems: Perfectly positioned at the bottom of suction pipes, it maintains primed pipelines and prevents the detrimental effects of dry running.
- Industrial Pipelines: Essential for water treatment and oil transportation. Horizontal pipelines that require vertical lift structures are recommended for DN50 and above.
- Special Media: Our corrosion-resistant models expertly handle weak acids and alkalis, though high-viscosity or solid-laden fluids should be avoided.
Installation & Maintenance
1. Installation Guidelines
- Ensure vertical installation to facilitate optimal disc operation.
- Prime the suction pipe before the first startup to establish a necessary vacuum.
- Clean sealing surfaces meticulously and seal pipeline ends during prolonged storage.
2. Maintenance Tips
- Regular lubrication of the valve stem is essential; avoid using levers for forced operation.
- Prompt replacement of worn sealing rings is crucial; certain models offer quick access for maintenance.
