Foot Valve Manufacturers in USA

Valvesonly are the leading Foot Valve Manufacturers in USA. A foot valve is a type of valve which is installed at the bottom of a vertical pipe or pump suction line. Its primary function is to prevent the backflow of fluid from the discharge line back into the pump or sump when the pump is not operational. The valve consists of a body with an inlet port, an outlet port, and a flap or disc that opens to allow fluid to flow into the pump when it is started and closes to prevent backflow when the pump is turned off.

How Foot Valve works?

The operation of a foot valve is relatively simple. When the pump is turned on, it creates suction that draws fluid through the valve and into the pump. As fluid enters the valve, the pressure from the incoming flow pushes the flap or disc open, allowing the fluid to pass through and into the pump. When the pump is turned off, the pressure differential changes, causing the flap or disc to close under its own weight or with the help of a spring, thus preventing the fluid from flowing back into the suction line. This ensures that the pump remains primed and ready for operation when needed, without the risk of losing prime due to backflow.

How to install foot valve?

Select an appropriate spot in the water source (like a well, lake, or reservoir) from which to extract water. Make sure the location is reachable for maintenance needs. Prior to installation of the foot valve, make sure to clean the pipe ends and eliminate any debris or obstacles that may disrupt the valve's function.

Position the foot valve in the correct orientation for installation. The valve should be installed at the bottom of the suction pipe, with the inlet facing downward to allow water to flow into the valve.
Connect the foot valve to the suction pipe with suitable fittings or couplings. Make sure the valve is tightly secured to avoid leaks or shifting while in use.
Verify that the foot valve is positioned correctly, with the inlet pointing downwards and the outlet attached to the suction pipe going to the pump.
If necessary, prime the pump to remove any air from the system and create a vacuum that will allow water to be drawn into the suction pipe and foot valve.
Once the foot valve is installed, test its operation by activating the pump and monitoring the flow of water. Check for any leaks or abnormal noises that could indicate a problem with the installation.
After checking whether the foot valve is working properly, secure all connections and fittings to prevent loosening or leaks during operation.
Schedule regular inspections and maintenance to ensure that the foot valve continues to function correctly. This may include cleaning the valve and inspecting to check for any damage or wear.

When to use a foot valve?

Foot valves are typically used in applications where a pump needs to draw water or other fluids from a water source such as a well, lake, or reservoir. Here are some situations where a foot valve might be used:

Well Water Systems
Surface Water Intake
Irrigation Systems
Dewatering Applications
Sump Pump Systems
Fountain and Water Feature Systems

How to test Foot valve?

Before testing the foot valve, check for any damage, corrosion, or wear. Check the valve body, sealing surfaces, and connections for leaks, cracks, or other defects.

Make sure that the suction line and foot valve are clear of any blockages or debris that might disrupt the test or impact the valve's efficiency.
Close the discharge valve or outlet of the pump to prevent water from flowing out during the test.
Monitor the movement of water in the intake tube. The foot valve is designed to open by itself, permitting water to flow into the suction line and pump.
Check the pressure gauge on the pump to ensure that it builds up to the desired level. If the pressure does not increase or remains low, it could indicate a problem with the foot valve or suction line.
During the operation of the pump, check the foot valve and connections around it for any indications of leaks or unusual behavior. Leaks might suggest a defective seal or a loose connection that requires attention.
Once the test is complete, turn off the pump and observe the behavior of the foot valve. To avoid water flowing back into the suction line, it must shut down automatically.

If any issues were identified during the initial test, repeat the testing process after addressing the problem to ensure that the foot valve functions properly.

Can a foot valve be installed horizontally?

Typically, foot valves are designed to be installed vertically at the bottom of a suction line or pipe. This vertical orientation allows the valve to function effectively by utilizing gravity to keep it primed and prevent air from entering the system. However, there are some cases where foot valves can be installed horizontally, although this is less common and may require specific considerations like-

In situations where there is limited vertical clearance or space constraints, installing a foot valve horizontally might be necessary to accommodate the system layout.
Some foot valves are designed specifically for horizontal installation. These valves might have built-in strainers or adjusted internal mechanisms to guarantee correct functioning when positioned horizontally..
Horizontal installation can potentially lead to sediment or debris accumulation inside the valve, which may affect its performance over time. Regular maintenance and cleaning may be required to prevent blockages and ensure smooth operation.
Proper priming becomes critical when installing a foot valve horizontally. Ensuring that the valve and suction line are adequately primed before starting the pump is essential to prevent air pockets and maintain consistent water flow.
