4 Basic Parts Of A Foot Valve
There are a lot of foot valves out in the market right now, each having specific sizes and made of different materials for various applications. However, even if these foot valves all differ in sizes and applications, they all have several components that are common to all of them. Despite the fact that these valves are seldom seen since they are always under water or at the bottom of a well, it would still be better to know what parts a basic parts has to know how it simply works. Here are the basic parts that can be found in all valves of this kind.
All foot valves have screens so that they can keep out any debris or sediments that may come up from the suction end of a pump line. These screens are commonly made of materials that do not corrode easily like plastic, stainless steel and brass. Even if this is just a simple screen, it has a very important role in the efficiency and lifespan of the valve. Plastic screens are commonly used for light duty jobs like small tanks and the more heavy duty jobs are made either of stainless steel or brass materials.
We all know that this is the most important part of the valve because all of the mechanism is housed within the body. Materials that are commonly used for the body is cast iron and brass for those heavy duty valves. Valves with these kinds of bodies are also put to use for high pressure and heavy duty loads and can be more than 10 inches in diameter. Smaller ones are mostly made of hard plastic, PVC or stainless steel. These valves are used for lower pressures and lighter duties.
This is also an important part of a foot valve because the seat is where the valve lands when a pump is turned off. The seat is an integral part of the body and this is where the o-ring, either made of rubber or silicone, is placed as well to avoid leaking when the valve is closed. Since fluids pass through the seat and the rings always, this is one of the parts of the valve that may wear down faster than the rest of the device.
This is basically the door or gateway of the valve. Once the pump is turned on and the water starts to flow up the valve, the disc raises, enabling water or any fluid to come through. Discs are most commonly made of heavy grade metals like bronze, brass or steel which has a longer lifespan than plastics or stainless steel.
These are the main parts that can be found on a foot valve. Of course, different companies have different technologies in making their own valves. If you would look at some foot valve review, you would notice that even some check valves and ball valves can be converted into foot valves. Knowing what the parts are for these non-return valves will definitely help out also in having the proper maintenance for these devices.
