Detailed Description for Foot Valves

A foot valve is a component used with a pump to help the pump stay geared up, ensuring that when people turn it on, it will instantly begin pumping water. Foot valves are found in wells, attached to pool cleaners, and in other settings where fluids are being pumped. The valve permits the pump to be turned on and off without bothering about whether the pump will stay primed and it also filter fluids pulled into the line to lessen the risk of clogs.

Foot valves are a form of check valve, a valve that only allows flow in one direction. In the case of a foot valve, fluid can be pulled into the valve and up the line, but it cannot flow back out. When the pump is on, water moves through the valve, into the line, and into the pump itself. When the pump is turned off, the water in the line remains in place because the valve checks it from flowing backward. If the water was permitted to drain out of the line, air would end up in the line and the pump would need to be primed again to get it flowing.

These devices are usually concealed from view, making it difficult for people to conclude when they need cleaning and maintenance. The head is purposely designed large to ensure a smooth flow of water, but if the water becomes sluggish, it can be a sign that there is something wrong with the foot valve and it needs to be pulled up for the check.

Brass, plastic, and other noncorrosive materials are preferred for the construction of a foot valve. These materials are hard-wearing and will last for a long time. They also tend to be more expensive to work with and subsequently foot valves tend to be pricey. When purchasing a foot valve, buyers weigh the initial cost against the valve's expected life. Many companies offer extended guarantees for their products, promising consumers that they will replace valves if they fail unexpectedly.

 

Features:

·         Rigid and sturdy design with minimum loss of head across the valve

·         Perfectly flat seating surfaces for good sealing
