Structure & Working Principle
1. Core Components
This exquisitely engineered foot valve comprises vital components including a robust valve body, precision valve disc, secure valve cover, durable bushing, and high-quality sealing ring, each meticulously designed for optimal performance. The valve operates seamlessly, opening under fluid pressure to allow smooth liquid inflow. As soon as the pump ceases operation, outlet-side pressure promptly seals the disc, effectively preventing any backflow.
2. Design Features
- Anti-Clogging Design: Ingeniously designed with multiple inlet ports and reinforced ribs on the valve cover to significantly diminish blockage risks when dealing with media containing minor impurities.
- Connection Types: Versatile connection options are available, supporting both threaded (screwed) and flanged connections, catering to a wide array of pipeline requirements.

Applications
- Pump Systems: Essential for installation at the base of suction pipes, this valve ensures that pipelines remain primed, effectively preventing dry running and maintaining system efficiency.
- Industrial Pipelines: Versatile usage in water treatment and oil transportation sectors. For horizontal pipelines, vertical lift structures are advised (especially recommended for DN50 and above).
- Special Media: Designed for handling corrosion risks, our models effectively manage weak acids and alkalis. It's best to avoid use with high-viscosity or fluids laden with solids.
Installation & Maintenance
1. Installation Guidelines
- Vertical installation is crucial to ensure the valve disc operates correctly, ensuring optimal performance and longevity.
- Prior to initial startup, prime the suction pipe to create the necessary vacuum for efficient operation.
- During extended storage periods, clean sealing surfaces meticulously and securely seal pipeline ends to maintain integrity.
2. Maintenance Tips
- Regular lubrication of the valve stem is essential; refrain from using levers that enforce operation to prevent damage.
- Prompt replacement of worn sealing rings is crucial; certain models are designed for quick maintenance access, ensuring minimal downtime.
