Swirl valve - flow limiter
Swirl valve and flow limiter
A swirl valve is a specific type of flow restrictor used to control the flow of fluids. It works on the principle of eddy currents, in which the liquid is guided through a constriction, creating a vortex. This vortex slows down the speed of the flow and limits the flow rate. One of the benefits of using a swirl valve as a flow restrictor is that it provides precise control over the flow. The swirl allows the flow rate to be precisely adjusted to the desired value, making it suitable for applications where a constant and precise flow is required. In addition, a swirl valve is also relatively easy to install and maintain, which increases ease of use. Another advantage of a swirl valve flow limiter is that it offers high resistance to contamination. The construction of the valve means that dirt particles are less likely to get stuck, reducing the risk of blockages and wear. This makes the swirl valve extremely suitable for applications in environments where the fluid contains many contaminants. In short, a swirl valve flow limiter is an effective and reliable way to control the flow of fluids. With its precise control, easy installation and maintenance, and high resistance to contamination, it is a widely used instrument in various industries and applications.
Better coordination of your flow when using a swirl valve
Better coordination of the flow rate when using a swirl valve offers several advantages. Firstly, it ensures more efficient operation of the swirl valve itself. By accurately regulating the flow, the valve can function optimally and deliver the desired performance. In addition, it also offers optimal control over the flow rate. Users can adjust the flow rate precisely to their specific needs, giving them more flexibility in using the valve. Another advantage is that better coordination of the flow rate extends the life of the swirl valve. The valve is not unnecessarily burdened by a flow that is too high or too low, which reduces wear and extends its lifespan. In addition, better coordination of the flow rate results in less pressure loss when regulating it. This means that less energy is required to control the flow, resulting in lower energy costs and more efficient use of resources. In short, better coordination of the flow rate when using a swirl valve offers numerous advantages, including more efficient operation, optimal control, a longer lifespan and less pressure loss.
Easy to install
A major advantage of a swirl valve and flow limiter is that no complicated installation is required. This means that no special tools are required to install the valve. In addition, the swirl valve is suitable for both horizontal and vertical installation, making it flexible in use and can be installed in different locations. In addition, the fast and efficient installation makes it possible to have the valve operational quickly. This makes the swirl valve and flow limiter easy to install and very suitable for various applications.
CE marking of the heart of rainwater management
The swirl valve and the flow limiter play a crucial role in rainwater management. These components ensure that rainwater is drained in an efficient and controlled manner. The swirl valve is an ingenious device that ensures optimal water flow. It creates a vortex in the water, which distributes the pressure evenly and prevents blockages from forming. In addition, the swirl valve is equipped with a flow limiter, which ensures that the water is drained at a certain speed. This is very important to prevent overloading the sewer system. Both components have a CE marking, which indicates that they comply with European directives in the field of safety, health and the environment. The CE marking is, so to speak, the heart of rainwater management, because it indicates that these components are reliable and safe to use.
Operation of a swirl valve
A swirl valve is a type of control valve used to control the flow of fluids. It works on the principle of eddy currents, where the flow of the medium is disturbed by a specially designed internal construction. This ensures that the speed of the medium is increased and vortices are created. These vortices act as a kind of obstacle to the flow, limiting the flow. The swirl valve can therefore serve as a flow limiter. The operation of a swirl valve can be explained on the basis of several points. First of all there is the internal construction of the valve, which consists of a number of discs with radial slots. These slots ensure that the medium is guided in eddy currents. In addition, there is the shape of the inlet and outlet of the valve, which also contributes to the creation of these eddy currents. The flow limiting effect of a swirl valve is based on the fact that the eddy currents disrupt the flow of the medium and cause turbulence. This increases the resistance in the valve and reduces the flow rate. This can be useful in situations where a constant and controlled flow is desired, such as in heating systems or cooling systems.
Applications of a swirl valve
A swirl valve is a versatile device that has different applications in different industries. One of the most important applications is to control flow rate and pressure. This ensures efficient operation of the system. In addition, the swirl valve is also widely used in industrial processes, such as chemical production and oil and gas extraction. In these applications, the swirl valve can regulate the flow of fluids to create a safe and controlled working environment. Furthermore, the swirl valve is also used in water treatment systems, where it can regulate the water flow. This is essential to enable the correct treatment of water and ensure its quality. Finally, swirl valves also find application in irrigation systems, where they are used to control the water supply. This helps in efficient use of water resources and optimization of irrigation processes. All in all, the swirl valve offers various advantages and possibilities in different industries and systems.
The centrifugal flow regulator, type CEV, with European technology verification is manufactured for a specific capacity, typically within a capacity range of 0.2 l/s to 80 l/s (see diagram). The flow controller is used for small to moderate amounts of rainwater and certain types of industrial wastewater.
The design of the centrifugal flow controller provides an average water discharge/flow that is significantly higher than other simple flow control techniques. It has steeper current control characteristics and can maximize discharge at both the 'peak' of the characteristic and the design point (h design, Q design). See an illustration of this in the characteristic of the CEV controller.
This ideal design gives the centrifugal flow controller unique properties for regulating the flow. That is why our flow regulators have the largest openings and therefore the lowest risk of blockage. Moreover, the inlet is not separated by partition walls or the like. The larger the opening, the smaller the risk of blockage.
During operation, the flow opening of the flow controller remains unchanged; it does not gradually decrease as the water level rises, as is the case with some flow-control techniques.
The inlet of the flow controller is from below. This ensures that there is a water seal and that the closing water column is as high as possible.
The CEV regulator has an adjustable inlet opening. The inlet opening is infinitely adjustable and can be set to ±25% of the average water discharge/flow. The setting interval for each individual flow controller varies. The flow controller is also available with a replaceable outlet baffle that allows further adjustment of capacity.
The flow regulator is the only one on the market whose capacity can be adjusted on site without the need to replace any components: two screws are loosened with an Allen key and the opening is adjusted. If you would like to change the capacity, please contact us. We identify the flow controller by its reference number and then calculate the opening setting for the new capacity.
A CEV flow controller is available with coupling (wedge coupling) and a tie rod to facilitate easy, clean installation and disassembly from the ground. This allows inspection, service or capacity changes of the flow controller to take place under ideal hygienic and working conditions.
By equipping the flow controller with a closed coupling claw at the front, the flow control options are as follows:
- Throttle effect when the flow controller is in the normal position
- Close by turning the flow regulator 180° around a vertical axis. This option can be useful in the event of an accident with a tanker truck, etc.
- Bypass when the controller is disassembled/lifted off.
Often the centrifugal flow controller can be built into existing or designed chambers or tanks as it takes up very little space; there must be a collection container.
