To use water efficiently, the flow rate must be precisely regulated. NEOPERL flow regulators adjust the water flow rate to meet your requirements. They optimize water consumption in household faucets or are installed as sub-components in drinking water supply lines for technical applications.
Functions of a flow regulator
Keeping the flow rate constant
Irrespective of pressure fluctuations, our flow regulators ensure a virtually constant flow rate. This allows water-saving requirements and official standards to be met.
Uniform water distribution
NEOPERL flow regulators ensure uniform water availability at rows of washbasins or at all outlet points in a multi-story building, mitigating the effects of pressure fluctuations.
Correct control of the water stream
For water stream control, flow regulators control the force and range of the stream. The gentle flow of water aids careful cleaning of the eyes, e.g., in eye showers.
Precisely dosed quantities
In combination with solenoid valves, our regulators ensure that coffee and drinks machines, as well as industrial filling plants, dispense the correct volume of liquids.

How do flow regulators work?
A typical flow regulator consists of three components:
- a housing
- a seating area
- a precision o-ring
The flow rate is determined by the interaction between the seating area and the o-ring. When water flows through the regulator at a higher or lower pressure, the shape of the o-ring changes.
Static state (no flow; no pressure or low pressure): The o-ring is relaxed (position 1).
Dynamic state (flow): When water flows through the flow regulator, the shape of the o-ring changes and it is pushed into the seating area. This reduces the amount of space for the water to pass through (position 2).
The higher the flow pressure, the more the shape of the o-ring changes (position 3).
As the pressure decreases, the o-ring gradually returns to its original shape, making larger spaces for the water to pass through again (back to positions 2 and 1).
In this interaction, the o-ring and seating area adapt to the changing pressure conditions. A constant flow rate within the specified tolerance is ensured.

Outstanding life cycle assessment
A NEOPERL flow regulator in the shower head saves water and energy when showering. But:
- How much water and energy are used in the production and disposal of the product?
- How much CO2 is released during transport?
- What is the real relationship between costs and savings?
To answer these questions, the Technical University of Berlin conducted a life cycle assessment study on behalf of Neoperl. The results were astonishing:
If a small flow regulator is in use for ten years, it recovers at least 26,000 times the resource consumption from the manufacturing process. The use of the flow regulator therefore pays off after just a few days, both for you, mankind and the environment.
