Stainless Steel Screw Foot Valve
Product Description
Structure & Working Principle
1. Core Components
Precision-engineered, the foot valve boasts a robust assembly of components: the valve body, disc, cover, bushing, and a high-quality sealing ring. When fluid pressure is exerted upon the disc, it gracefully swings open, allowing the seamless flow of liquid. As the pump ceases operation, the outlet side pressure swiftly seals the disc, effectively blocking any potential backflow.
2. Design Features
- Anti-Clogging Design: Ingeniously crafted with multiple inlet ports and sturdy reinforced ribs on the valve cover, this feature expertly minimizes the risk of blockages, even in media with minor impurities.
- Connection Types: Versatility at its finest, supporting both threaded (screwed) and flanged connections to cater to a variety of pipeline requirements.

Applications
- Pump Systems: This product is adeptly installed at the base of suction pipes, ensuring pipelines remain primed and mitigating the risk of dry running.
- Industrial Pipelines: Ideally suited for use in water treatment and oil transportation. For horizontal pipelines, vertical lift structures are recommended for diameters DN50 and above.
- Special Media: Crafted for resilience, corrosion-resistant models are capable of handling weak acids and alkalis. However, high-viscosity or solid-laden fluids are not recommended.
Installation & Maintenance
1. Installation Guidelines
- For optimal performance, it must be installed vertically to ensure the disc functions flawlessly.
- Prior to the initial startup, ensure the suction pipe is primed to establish a vacuum.
- Safeguard sealing surfaces and seal the ends of pipelines if the valve is to be stored long-term.
2. Maintenance Tips
- Regularly lubricate the valve stem to ensure smooth operations; avoid applying force with levers.
- Promptly replace any worn sealing rings. Some models are designed to allow quick and easy maintenance access.
