Underwater and Submerged flow control valves need to be suitable to your application. Contact us for more information.



Facts about Foot valves:

  • Originally named a Foot valve from being installed in the foot of a well many years ago.
  • The Foot valve is an Underwater Valve. If not water, it's a Submerged Valve in some type of fluid.
  • The foot valve is a useful flow control valve and has 3 functions. The foot valve not only acts as a back flow preventing device, it also stops large debris from being sucked into the pump system, and keeps the pump suction line primed.
  • Foot valves are easy to install, and when good quality they are very reliable. 
  • Selecting the most suitable material for your unique application is very important, as the valve will always be underwater or submerged in a fluid. A stainless steel foot valve will always outlast a galvanised foot valve.

General information about Foot valves:

  • A soft rubber seat for the valve disc to close on to is essential for a 100% seal and no loss of prime.
  • The foot valve is a cheap way to prime a pump, installed at the pick up end of the suction line.
  • The strainer part of a foot valve needs to be cleaned regularly to keep the holes clear so the valve and pump can keep running properly with no restriction, providing good flow results.
  • The quick release lever on a foot valve allows the user to remotely force the valve disc open, releasing water or fluid out of the suction line. This is done by attaching a cable to the hole drilled into the end of the lever, and running the cable up the suction line to the pump. This feature is very useful as foot valves are normally positioned in hard to reach places.
  • The foot valve opens by the pump suction when the pump is operating, water or fluid is sucked up into the pump.
  • When the pump is turned off, suction stops and gravity force comes in to play, making the water already in between the valve closure area and the pump suction flange fall back down, the weight of this water or fluid will act on the swinging valve disc forcing it to close.
  • The weight of the water or fluid on the valve disc, is what provides the 100% tight seal.

The purpose of a Foot valve:

  • Foot valves are used underwater or submerged in a fluid to extract water or fluid for a specific purpose and ensuring a pump will never run dry, never be damaged by a piece of debris, and always be primed.
  • A foot valve is installed to keep a pump primed. This is done by controlling the direction of water flow to avoid water or fluid loss in a suction line. As soon as the pump stops the valve closes.
  • It is important to use a foot valve on a pump suction line because it prevents dry running which will essentially damage the pump.
  • The strainer part of the foot valve keeps out large debris to protect the pump and maintain a good sealing surface for the valve disc closure.
  • Our foot valves are designed to have a large unrestricted area for suction and minimal pressure drop.

The table below provides an overview of the Foot Valve product range:

Model Size range Pressure rating rate
Galvanised Foot Valve - flanged Table D AS2129 DN80 (3") to DN750 (30") 350kPa / 35 Meters of water
316 Stainless Steel Foot Valve - flanged Table D AS2129 DN80 (3") to DN600 (24") 350 kPa / 35 Meters of water
Poly HDPE Foot Valve - flanged Table D AS2129 DN100 (4") to DN300 (12") 200 kPa - 300kPa / 20 - 30 Meters of water

Note: As a Foot valve is used on a suction line, they are not designed to have a high positive pressure rating. The pressure rating of 35 Meters is from the check valve after the pump discharge, to the foot valve.

Common Applications:

  • Mine de-watering
  • River
  • Reservoir
  • Lake
  • Pond
  • Flooded area
  • Underground Well
  • Storage tank

How to service a Foot valve:

  1. Foot valves are very easy to inspect once they have been pulled up from the water.
  2. A clear sign and symptom that a foot valve needs to be serviced is when you notice a restriction in the flow rate, or if the pump is losing prime.
  3. Once you have pulled the valve up from the water or fluid, check the strainer holes to make sure there is no blockage, and inspect the rubber valve seat. Look for any split, missing rubber, or piece of debris stuck and preventing full valve closure.
  4. Foot valves will only operate efficiently when the rubber valve seat is in good condition, and when the strainer holes are clear.
  5. Also check that the swinging valve disc is swinging freely, and there is no issue with the hinge or pin.
  6. Also check for any missing parts, and missing nuts and bolts. This would be causing problems.
  7. If the foot valve is badly corroded, it will need to be replaced.

How to install a Foot valve:

  1. Once you have the Flanged Foot Valve, and is sized correctly for your pump suction line, and matches the pump suction line flange specification, you are ready to start the installation process.
  2. Check over the foot valve to make sure there are no loose bolts and no missing parts, as this would interfere with the performance of the valve.
  3. The flanged foot valve should be installed with a 3mm thick rubber gasket, that goes between the foot valve flange face and the mating flange face.
  4. Connect the two flanges together, with the rubber gasket in the middle and install the correct number of nuts and bolts. Using good quality nuts and bolts would be a good idea as they will be constantly underwater or submerged in a fluid.
  5. Tighten all nuts and bolts correctly in the required pattern.
  6. Flanged foot valves can be installed to flanged suction hoses, or flanged suction pipes, so long as there is a flange to bolt the valve to.
  7. Once the flanged foot valve is bolted to the suction pipe or hose, it can then be submerged to the required position. The valve will be ready to use.
