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.
