Top 3 FAQs

1. What does "17 dB (Class 1)" mean for noise levels? The NF Class 1 certification indicates that the valve is extremely quiet. 17 dB is comparable to the sound of rustling leaves or a quiet whisper, making it one of the quietest valves available.

2. Can this valve be used in both high and low water pressure environments? Yes. The operating range is exceptionally wide, from 0.1 bar (ideal for very low-pressure or tank-fed systems) all the way up to 16 bars (suitable for high-pressure city mains).

3. How do I adjust the water level in the cistern? The valve uses a screw adjustment mechanism. Simply turn the screw to raise or lower the float, setting the exact water level you require for efficient flushing.
