The non-return valve for water applications should be strictly considered in the sense that you choose other valves. Like all liquids and various other media, water has its own unique characteristics. These specific properties must be used KP-LOK in conjunction with the appropriate valve. In fact, it is a clear premise, but the choice of a complete perfect check valve may depend on a less obvious reason.
Problems with water transport
Water beating/hammering: This hydraulic phenomenon is observed with other liquids, but a water hammer occurs when the medium stops abruptly or changes direction. When water or any other medium in the pipeline moves in only two directions, this phenomenon can cause the pipeline to vibrate, creating a very common loud noise. Both can cause damage. Since it is almost impossible to maintain a stable flow indefinitely, the transport of water in many applications around the world is a difficult task. The most common cause of water hammering is when the pump stops without warning. Since the check valve can not be closed quickly, the water returns to the pump. The water hammeringis sometimes called water slam.
Water reverse flow: When not activated, the water (or the discharge of this fluid) flows in the opposite direction, so that the pump rotates in the opposite direction and is irreparably damaged. If the water moves in the wrong direction, it can also cause serious damage to the entire distribution system. Unlike check valves that consist of several check valves and lock with them, the check valves are not necessarily reliable. Reverse flow can occur.
The Valve Chatter: This valve chatter occurs when the valve is frequently opened or closed. The flap holder can damage the valve and piping and can completely fail.
Check the water problem
The check valves are very reliable, but new, better, and more innovative models are introduced each year, but all are designed to avoid the three problems above. The check valves operate independently of external factors such as power outages due to their simplicity, but are subject todesign features, flow direction and check valve faults.
There are two basic designs of check valves. One uses a disc (essentially a flap) and the other uses a floating ball. They are all one directional, which means that they stop water from backward flowing through pipes and systems. They both have their advantages and disadvantages but work just well with same success. But in the end, the success of the check valve is not too fast, but it is not too late, it depends on the action that can cause a water hammer or a repression. In addition, the behavior of the valve flap is due to an oversized general defect – it is not necessarily adapted to the application due to the compatibility of the valve.
Finally, as with most valves, the success of a check valve also depends on the tightness of the seal. When selecting a check valve, all this must be taken into account.
Our success in the treatment of water
We are committed to providing certified products for the treatment of water for the supply of drinking water. This is a key water treatment to remove and reduce existing water pollutants and make the water suitable for its end use. Our Ball Valves, Ball Valves, Swing-Flex Check Valves, Check Valves and Surge Buster Check Valves can be used for solid separation processes such asfiltration andsettling as well as chemicals such ascondensationand disinfection. After removing sediment from wastewater, check valves can be used to prevent backflow when the pump is not running. American butterfly valves are often used in compact dimensions, and many valves are installed to prevent the formation of air bubbles and vacuum, thus maintaining the flow efficiency of the pipeline. Our valves are durable, trouble-free and an integral part of water treatment.
