The Neoperl PCW 02 Flow Regulator (Part No. 58909410) is a high-performance water-control insert engineered to deliver a consistent flow of 12.0 litres per minute. Designed for taps, mixers and shower systems that require a stable but higher-volume flow, this regulator provides reliability, comfort and efficiency even when water pressure fluctuates.
With its robust construction and precise flow management, the PCW 02 is an excellent choice for both domestic and commercial installations where predictable water delivery is essential.
Key Features
Constant 12.0 l/min Flow
This regulator maintains a controlled and uniform 12 L/min flow rate, making it ideal for fixtures that require a stronger output such as kitchen taps, utility sinks, high-flow wash areas or certain shower installations.
Pressure-Compensating Design
The PCW 02 automatically adjusts to pressure changes within the plumbing system. Whether the water pressure rises or falls, the regulator stabilises the flow to ensure consistent performance and improved user comfort.
Compact and Versatile
Small in size and easy to install, the regulator fits neatly inside compatible faucet or shower fittings. Its compact design makes it highly suitable for retrofitting existing fixtures without requiring replacement of the tap or shower hardware.
Durable Construction
Manufactured with high-quality Neoperl components, the PCW 02 withstands daily use, varying temperatures and mineral exposure. Its long-life design ensures years of reliable operation with minimal servicing.
Improved Water Control
By limiting excessive flow at higher pressures, the regulator prevents unnecessary water waste while maintaining strong performance. This contributes to both comfort and improved system efficiency.
Applications
Kitchen taps requiring high yet controlled flow
Utility sinks and washroom taps
Commercial and industrial wash areas
Showers designed for higher flow rates
Buildings with variable or high water pressure
Hard-water regions requiring durable components
Water and Energy Benefits
Although the PCW 02 allows a higher maximum flow compared to low-flow regulators, it still provides significant efficiency gains by preventing overconsumption at high pressures. Instead of allowing water flow to spike uncontrollably, the regulator caps it at 12 L/min, improving predictability and reducing unnecessary water waste.
This also helps stabilise hot-water usage, supporting better energy efficiency for buildings with high-demand fixtures.
Installation and Maintenance Notes
Simple installation inside compatible mixers, taps or shower fittings
No specialist tools required
Suitable for both new installations and retrofits
Minimal maintenance — occasional inspection recommended
Performs reliably under a wide range of pressures
