Structure & Working Principle
1. Core Components
The foot valve, masterfully crafted with a body, disc, cover, bushing, and sealing ring, orchestrates a flawless fluid control. When fluid pressure graces the disc, the valve gracefully opens, inviting liquid inflow. Upon pump cessation, outlet-side pressure commands the disc to seal instantly, heroically averting backflow.
2. Design Features
- Anti-Clogging Design: Ingeniously engineered with multiple inlet ports and robust reinforced ribs, the valve cover skillfully minimizes blockage, even amidst media laced with minor impurities.
- Connection Types: Tailored for versatility, this valve effortlessly accommodates threaded (screwed) and flanged connections, adapting to a myriad of pipeline demands.

Applications
- Pump Systems: Strategically positioned at suction pipe bases, this valve ensures pipelines remain primed, steadfastly preventing dry runs.
- Industrial Pipelines: Ideal for water treatment and oil conveyance, especially in horizontal pipelines requiring vertical lift structures for sizes DN50 and above.
- Special Media: Triumphs in corrosive environments, handling weak acids and alkalis with ease. Avoids high-viscosity and solid-laden fluids for optimal performance.
Installation & Maintenance
1. Installation Guidelines
- Ensure vertical installation for impeccable disc functionality.
- Prime the suction pipe at the outset to cultivate a seamless vacuum.
- Maintain clean sealing surfaces and securely seal pipeline ends during prolonged storage.
2. Maintenance Tips
- Consistently lubricate the valve stem; abstain from leveraging forceful tools.
- Swiftly replace any worn sealing rings. Certain models offer expedited maintenance access for your convenience.
