Normal foot valve

The normal foot valve is a lift‑type check valve. It is specially installed at the extreme end of the pump suction pipe and must be fully submerged under water. Its core function is to prevent medium back‑flow in the pipeline after pump shutdown and retain water inside the suction pipe, so that no refilling is needed when restarting the pump. The valve body is equipped with an integrated strainer to intercept large‑sized impurities such as stones and weeds, avoiding foreign matter from entering and damaging the pump impeller. Designed mainly for clean‑water service, the normal foot valve offers excellent cost‑performance and serves as a commonly‑used auxiliary valve for agricultural water intake and water‑supply & drainage systems.

Detail

Parameters

The normal foot valve is a lift-type check valve specially designed for pump suction pipelines. It is installed at the lowest end of the

suction pipe and must be fully submerged in water during operation. Equipped with an integrated strainer, the valve effectively

blocks large impurities such as weeds and stones, preventing foreign matter from entering the pump and damaging the impeller to

achieve reliable anti-clogging and pump protection. After the pump stops running, the foot valve automatically seals and locks

water to prevent medium backflow, retaining water inside the suction pipe permanently. This eliminates repeated water filling during pump restart and greatly simplifies operation while improving working efficiency.Featuring simple and sturdy structure, low flow resistance,

sensitive opening and closing, and reliable sealing, this foot valve is specially developed for clean water conditions, suitable for well water, river water, tap water and other clean media. With high cost performance and easy installation and maintenance, it is a widely used standard supporting valve for farmland irrigation, municipal water supply and drainage, industrial circulating water and water conservancy water

intake projects.

Five Core Advantages

1. Excellent Water Lock & Anti-backflow Performance

This foot valve adopts lift-type sealing structure, which can automatically and tightly seal when the pump stops working. It effectively

locks water in the suction pipeline and prevents medium backflow. The pump can be restarted directly without manual water refilling,

greatly saving operation time and improving working efficiency.

2. Integrated Strainer for Pump Protection

Equipped with an integral filter screen, the valve can effectively intercept weeds, stones, sediment and other large impurities in the water.

It avoids foreign matter entering the pump body and damaging the impeller, effectively preventing pipeline blockage and extending the

service life of the water pump.

3. Low Flow Resistance & Smooth Water Intake

The optimized through-flow structure features low water flow resistance and sensitive opening and closing. It will not affect the water

absorption efficiency of the pump, ensuring stable water supply and efficient pipeline operation without medium deposition.

4. Simple Structure & Easy Maintenance

The valve has a sturdy and compact overall structure with stable performance and strong durability. It is easy to install, disassemble and

inspect on site. Wearing parts can be replaced separately, bringing low later maintenance cost and high practicability.

5. Wide Applicability & High Cost Performance

Designed for all kinds of clean water working conditions, it is widely applicable to well water, river water, tap water, industrial circulating

water and other media. It is an economical and reliable matching valve for farmland irrigation, municipal water supply and drainage, water conservancy projects and industrial systems.
