Intricate Structure & Working Principle
1. Essential Core Components
The foot valve is elegantly composed of a valve body, valve disc, valve cover, bushing, sealing ring, and other integral parts. Upon fluid pressure application on the disc, it gracefully opens, allowing the seamless inflow of liquid. As soon as the pump halts, the outlet pressure swiftly prompts the disc to close, effectively preventing any backflow.
2. Distinctive Design Features
- Cutting-Edge Anti-Clogging Design: The valve cover boasts multiple inlet ports and fortified ribs to significantly reduce blockage risks, even in media with slight impurities.
- Versatile Connection Types: Accommodates both threaded (screwed) and flanged connections, catering to a wide array of pipeline requirements.

Diverse Applications
- Pump Systems: Strategically installed at the bottom of suction pipes, ensuring pipelines remain primed and preventing dry running.
- Industrial Pipelines: Ideal for water treatment, oil transportation, and more. Horizontal pipelines necessitate vertical lift structures, especially recommended for sizes DN50 and above.
- Special Media: Corrosion-resistant models adeptly handle weak acids/alkalis; not suitable for high-viscosity or solid-laden fluids.
Efficient Installation & Maintenance
1. Comprehensive Installation Guidelines
- Ensure vertical installation is executed to facilitate optimal disc functionality.
- Prime the suction pipe before the initial startup to establish a necessary vacuum.
- Keep sealing surfaces pristine and seal pipeline ends during extended storage periods.
2. Proactive Maintenance Tips
- Consistently lubricate the valve stem, refraining from forced lever operations.
- Swiftly replace worn sealing rings; select models provide easy maintenance access for quick solutions.
