Edson's Foot Valve w/ bronze strainer and Nitrile check valve keeps debris and stones out of your pump while maintaining a prime in the suction line. It come equipped with mounting studs on the strainer so it can be fixed for permanent installations. Ideal for boat bilge and sump application. This Edson Foot Valve has 2" FNPT (Female National Pipe Threads) for easy attachment to hose or pipe fittings ending with 2" MNPT (Male National Pipe Threads).

A foot valve is basically a check valve fitted to the end of the suction pipe leading to the pump. Its purpose is to keep fluid trapped in the suction pipe when the pump stops. Thus, maintaining a suitable prime for the pump. When the pump restarts, The suction created opens the valve, giving full flow to the pump inlet.it is used to maintain hydraulic pressure within the pipeline to keep the water flow in accordance with given setting. It comes with strainer used to remove residues which may block the smooth flow fluid inside the valve.

A foot valve is a type of check valve used in water systems. It is typically installed at the end of a pump or water line to prevent backflow. Foot valves strainer are also known as floor valves, bottom valves, or simply check valves.

Foot valves are designed to open and close with the flow of water. When water flow is stopped, the foot valve closes to prevent backflow. This type of valve is often used in irrigation systems, where water pressure can fluctuate. Foot valves can also be used in sewage and wastewater systems.

Foot Valve Strainer helps you maintain your prime, so you do not need to completely draw a vacuum again. Built in check valve closes when the drafting stops, thereby keeping the hose filled with water from the strainer up.NH (National Hose or...

A foot valve is an essential component in submersible and jet pump systems, like wells. A submersible pump and a jet pump have the foot valve on their intake suction line. Foot valves prevent water from flowing backward when the pump is off and keep the pump primed at all times. This article explores the various types and applications of foot valves.

Electric pumps are used to drive water from a lower level to a higher level. When the pump is turned off, the water may flow in the reverse direction due to gravity. One of the main functions of a foot valve is to prevent this reverse flow.

A foot valve is a non-return valve installed in a pump suction or at the bottom of pipelines to prevent water from flowing backward when the pump is off. The valve keeps the fluid trapped in the suction pipe when the pump stops, thus sustaining a suitable prime for the pump, and preventing pump burnout. When the pump restarts, suction opens the foot valve. The intake side of the foot valve has a screen that prevents larger debris from entering the valve and damaging the internal components.

Based on the internal configuration, there are different types of foot valves like membrane, ball, and spring types. For example, a spring foot valve opens when the pump operates, allowing the fluid to flow. When the pump is turned off, the spring closes the valve, stopping the fluid from flowing backward. Read our article on well foot valves for more details on the different foot valve types.

For most foot valves, users need to clean the strainers themselves. However, some pumps have self-cleaning strainers. In these pumps, a small portion of pressurized liquid (like water) returns to the strainer through special piping. The liquid is then distributed to a series of special nozzles. The liquid sprays outward through the strainer at an angle. This spraying makes the screen rotate continuously. Consequently, any attached debris blows off the strainer and moves away from the suction line.

Besides water pumps, many pneumatic systems use foot valves due to their ability to prevent fluid backflow and maintain the fluid column when the pump is off. Foot valves keep the pump primed in the following applications:

A strainer keeps out or filters debris, sediments, or solid particles that may come up from the suction line, clog or jam the foot valve, and damage the pump. It ensures efficient operation and a long lifespan of the valve.

The benefits of Sure-Flo self-cleaning strainers are the result of continuous engineering improvement. They are built better and offer superior cleaning to maximize the performance of your irrigation system.

Debris clogging your pump's intake is eliminated when you install a Sure-Flo SCS2 self-cleaning strainer. Gone are those annoying trips into the water to scrub away leaves, algae, or aquatic plants. Because this screen is always clean, your pump can operate at maximum efficiency. It will provide all the water and pressure it was designed to deliver.

A small amount of water is returned from the discharge line of the pump to the strainer. Inside, two special nozzles spray against the screen, causing it to revolve. Any debris (i.e. algae, aquatic plants, or leaves) attracted to the screen is blasted off every half revolution. Strainers operate in any position.

A conversion tube connects the foot valve to the strainer. The conversion tube easily slides over the strainer neck and is firmly secured with pre-installed stainless bolts. With the addition of this conversion tube, existing foot valves can also be modified to work with Sure-Flo self-cleaning strainers.

A ball check valve with a foot screen can be installed vertically or horizontally on the suction side of a pump. The foot valve is an optional ball check valve arrangement where a screen is fitted into the inlet end of a ball check valve. This screen is used to filter large debris and solids from a fluid to prevent damage to pumps, clogging of valves and to protect downstream instrumentation. Foot valves can be typically found anywhere there is a check valve used as an intake. This includes pump inlets, lift stations and drains.

The Foot Valve Strainer is inserted into chemical tank at the end of the suction line. Foot check valves prevent siphoning and loss of prime in diaphragm style pump. Peristaltic style pumps do not require the check valve function of foot strainer, though filtering particulates out of the chemical is recommended. The rollers in the pump head of a peristaltic style pump act as a check valve when the pump is not running, eliminating the need of the foot check valve for these pumps.

In a move to deliver even greater performance and flexibility to its lineup of atomized mist cannons for odour management and wide-area disinfection, BossTek has introduced a new model with a dosing pump to precisely meter additives such as surfactants, tackifiers, odour treatments and disinfectants. With a standard coverage area of more than 6,100 square feet (566 square meters) and adjustable stroke length and frequency (from one per hour to 100 per minute), the DustBoss DB-30 Injektor was developed in response to customer feedback as companies in a wide range of industries seek to maximize the effectiveness of this proven technology. When equipped with optional 359-degree oscillation, the coverage area is increased to a whopping 31,000 square feet (2,880 meters).

Lewis explained that while a large percentage of customers achieve their dust suppression goals using plain water, the new design relieves users of the need to measure and mix solutions to achieve superior performance in specific service environments.

The additive injection system can be specified for new equipment or retrofitted to existing DustBoss machines. It also can be paired with an array of options to suit different requirements. For example, BossTek offers a number of nozzle choices to deliver reduced flow rates, while maintaining excellent atomization of the airborne mixture. The new model can also be specified with a Variable Frequency Drive (VFD) to adjust plume size, and it can be outfitted to accommodate non-potable water sources.

The standard unit is equipped with 30 brass nozzles, which can also be specified in stainless steel or nylon for particular applications. The premium-efficiency, direct drive fan motor delivers 9,200 CFM of air flow (260.5 CMM), while the optional single-phase motor provides 8,000 CFM (226.5 CMM). Like its larger relatives, the design produces millions of 50-200 micron droplets per minute, using a common 5/8-inch (15.8 mm) garden hose for a water supply.
