Product Notes
This inlet valve delivers a steady flow rate of 0.15 l/s at 3 bars of working pressure. Suitable for a massive functional pressure envelope up to 16 bars, it functions excellently on both low-pressure gravity systems and high-pressure unvented direct setups. The float level can be easily tweaked without special tools to manage flush water depth.
