Structure & Working Principle
1. Core Components
Crafted with precision, the foot valve is composed of a robust valve body, efficient valve disc, a protective valve cover, durable bushing, resilient sealing ring, and other essential components. Designed to operate seamlessly, when fluid pressure is applied to the disc, the valve opens, allowing liquid to flow in smoothly. Conversely, when the pump halts, pressure from the outlet side efficiently closes the disc immediately, effectively preventing any backflow.
2. Design Features
- Anti-Clogging Design: Equipped with multiple strategically placed inlet ports and reinforced ribs on the valve cover, this design significantly reduces the risk of blockages, even in media containing minor impurities.
- Connection Types: Versatile in its adaptability, this valve supports both threaded (screwed) and flanged connections, catering to a wide array of pipeline requirements with ease.

Applications
- Pump Systems: Essential for pump systems, this valve is installed at the base of suction pipes to maintain primed pipelines, effectively preventing the risk of dry running.
- Industrial Pipelines: Ideal for use in industrial settings, such as water treatment and oil transportation. For horizontal pipelines, a vertical lift structure is recommended, especially for sizes DN50 and above.
- Special Media: Our corrosion-resistant models adeptly handle weak acids and alkalis. However, they are not suitable for high-viscosity or fluids laden with solids.
Installation & Maintenance
1. Installation Guidelines
- Ensure vertical installation to guarantee optimal disc operation.
- Priming the suction pipe is essential before initial startup to effectively create the necessary vacuum.
- For long-term storage, clean the sealing surfaces and securely seal the pipeline ends.
2. Maintenance Tips
- Regular lubrication of the valve stem is recommended; avoid the use of levers to force operation.
- Promptly replace worn sealing rings; certain models are designed for quick maintenance access.
