Structure & Working Principle
1. Core Components
The foot valve is ingeniously engineered with a robust valve body, precision-crafted valve disc, a durable valve cover, bushing, and a high-performance sealing ring among other key components. Activated by fluid pressure, the disc majestically opens, accommodating seamless liquid inflow. Upon the cessation of pump activity, the outlet-side pressure immediately swings the disc shut, skillfully preventing any backflow.
2. Design Features
- Anti-Clogging Design: The intelligent design features multiple strategically positioned inlet ports and fortified ribs on the valve cover, effectively minimizing the risk of blockages in media laced with minor impurities.
- Connection Types: Engineered for versatility, the valve supports both threaded (screwed) and flanged connections, accommodating a wide spectrum of pipeline requirements with ease.

Applications
- Pump Systems: Strategically installed at the base of suction pipes, it ensures pipelines remain primed and safeguards against dry running.
- Industrial Pipelines: Perfect for water treatment, oil transportation, and more. Horizontal pipelines that hinge on vertical lift structures are recommended for sizes DN50 and above.
- Special Media: With corrosion-resistant options, this valve adeptly handles weak acids and alkalis while advising caution with high-viscosity or solid-laden fluids.
Installation & Maintenance
1. Installation Guidelines
- For optimal performance and efficient disc operation, ensure vertical installation.
- Always prime the suction pipe before the initial startup to establish a requisite vacuum.
- For extended periods of inactivity, clean sealing surfaces diligently and secure pipeline ends.
2. Maintenance Tips
- Consistently lubricate the valve stem to ensure smooth operation; avoid using levers for forceful operation.
- Promptly replace any worn sealing rings; select models offer convenient access for rapid maintenance.
