This 45 Degree Female Thread Foot Valve is made out of lightweight and durable aluminum.

This 45 degree foot valve attaches to a NPT thread end; hose, steel pipe, or PVC.

Note: Every valve will leak if there is no head pressure pushing down and sealing the flapper. Head pressure comes from the vertical down pressure of the volume of water above the valve. The weight of the 4 vertical feet of head pressure will push down and seal the valve. Below is a diagram showing how to measure the four feet of vertical lift from the water surface up to the centerline of the pump.

Description

Description

In irrigation systems, a 45-Degree Female Thread Foot Valve is a specialized component installed at the intake end of a suction line. It allows water to flow into the pump while preventing backflow, thereby maintaining the pump’s prime and enhancing operational efficiency.

Key Features:

45-Degree Angle: The valve’s 45-degree design is ideal for suction lines that are positioned horizontally or at a slight incline. This orientation ensures optimal seating of the flapper against the valve’s seat ring, promoting effective backflow prevention.
Female NPT Threads: Equipped with National Pipe Tapered (NPT) female threads, the valve facilitates straightforward attachment to hoses, steel pipes, PVC, or HDPE pipes, ensuring compatibility with various piping systems
Durable Construction: Typically constructed from lightweight yet robust materials like cast aluminum, the valve offers durability and corrosion resistance, making it suitable for diverse environmental conditions.

Applications:

Agricultural Irrigation: Ensures a consistent water supply to pumps drawing from sources such as ponds, rivers, or reservoirs, which is crucial for effective crop irrigation.
Industrial Fluid Handling: Maintains pump prime in systems requiring the transfer of various liquids, thereby enhancing operational efficiency.

Benefits:

Prevents Backflow: The flapper mechanism effectively stops water from flowing back into the source, maintaining the pump’s prime and preventing potential damage.
Enhanced Efficiency: By maintaining prime, the valve reduces the need for manual re-priming, leading to more efficient pump operation.
Ease of Installation: The female threaded design allows for quick and secure connections to existing piping systems, facilitating straightforward installation.

Considerations:

Proper Sizing: Ensure the valve size matches the suction line’s diameter to maintain optimal flow rates and system performance.
Maintenance: Regular inspection and cleaning of the valve and its screen are recommended to prevent debris buildup and ensure continuous efficient operation.

In summary, the 45-Degree Female Thread Foot Valve is a vital component in irrigation systems, providing reliable backflow prevention and maintaining pump efficiency, which are essential for effective water management.
