Kobold REG flow restrictors maintain constant quantities of liquids in pipework systems. These rate regulators are ideally suited for the simple restriction to a pre-set throughput value of water, or liquids similar to water. The flow restrictors ensure equilibrium, particularly in systems with many users and resulting pressure fluctuations caused by random flow conditions. This ensures that the desired throughput is not exceeded. Constant flow is achieved by two stainless steel diaphragms that are cross-mounted and riveted together.
The gap between the spring-loaded stainless steel plate and seal face is continuously varied as the differential pressure changes. As the differential pressure decreases the gap widens, and it closes as the pressure increases, thus maintaining a constant flow volume through the device.
Optimised water distribution is one example of application possibilities for REG, and specifically the regulated supply of fresh water to remote settlements. Initially, core settlements consume too much water, so that bottlenecks can occur at the remote end of the pipeline. Direct installation of REG completely eliminates the problem. The REG system offers advantages such as tamper-proof application, being maintenance-free for life, and it is a low-cost unit, requiring no auxiliary power.
Pump protection is another ideal application of REG, wherever a constant flow rate is needed despite pressure fluctuations: for example, switching on or off water consumers. In cooling circuits, REG offers lifelong protection against overheating at idle, water hammer and cavitation.
Industrial areas are another area in which the regulator finds good application, as virtually every industry needs water. REG’s high-quality stainless steel design is completely maintenance free, independent from auxiliary power and totally tamper proof, making it suitable for diverse industrial requirements, including district heating systems, cooling circuits, filtration processes, spray moisture applications, dosing applications, agricultural irrigation, firefighting and fire protection services, emergency shower systems (hazardous areas) and water treatment.
