Resideo FV300 Filling Valve Float Controlled
Introducing the Resideo FV300 Float Controlled Filling Valve, an essential solution for water supply systems in both industrial and commercial applications. This valve is designed for efficient filling of reservoirs, tanks, and cisterns. Its operation is managed through a float valve linked to the main storage medium via impulse link pipework. To prevent continuous filling, the valve features a pilot valve that can be finely adjusted, allowing for varying differential fill levels that control the valve’s opening and closing mechanism.

Resideo Braukmann D15S Pressure Reducing Valve
The Resideo Braukmann D15S is a highly regarded pressure reducing valve (PRV) commonly used across the UK and Europe for drinking water applications. This essential device serves to safeguard domestic water systems from excessive supply pressure, ensuring optimum performance and longevity. It is also suitable for industrial and commercial applications within its specified range. By installing a pressure reducing valve, you can effectively prevent damage caused by high pressure and reduce overall water consumption. The D15S maintains a consistent set pressure, even amid significant fluctuations in inlet pressure. Furthermore, by regulating the operating pressure, this valve minimises flow noise within the system, enhancing comfort and efficiency.
