Flow Limiters

A flow limiter decreases water flow rate in home or industrial applications. They are positioned in the flow path, effectively decreasing the water's travel space. This reduces the flow output; for example, a 5 litre per minute flow rate is lowered to a 2 litre per minute.


What Do Flow Limiters Do?


Flow limiters act as a barrier to the flow, reducing the area to travel through. This reduces the flow output, resulting in fewer litres per minute emitted by the pipe or hose. Slowing down the flow rate reduces the overall amount of water used per minute.


How Do Flow Limiters Work?


Two stainless steel spring plates crosswise mounted and riveted together in our industrial flow limiters achieve constant flow. As the differential pressure fluctuates, the space between the spring-loaded stainless-steel plate and the seal-surface changes continually. The gap expands as the differential pressure falls and closes as the pressure increases, resulting in a constant flow volume through the device.


Where are Industrial/Commercial Flow Limiters Used?
