## Long description

The Afriso Automatic Filling Valve FA 1/2" model 42405 is a compact control valve for automatic replenishment of water in closed heating and similar systems. Designed for connection to 1/2" fittings, it maintains the set operating pressure by allowing fresh water into the installation when pressure drops below the set point. The valve is suitable for domestic and light commercial heating circuits and boiler installations where regular pressure top-ups are required without manual intervention.
Advantages
This filling valve provides reliable automatic pressure maintenance, reducing the need for manual topping-up and minimizing downtime. Its 1/2" connection size fits common plumbing fittings, simplifying installation. The valve construction is intended for stable operation in closed systems and helps protect boilers and heating equipment from negative effects of low pressure.
Suitable for
Domestic heating systems and radiators
Small commercial boiler installations
Closed-loop hot water circuits that require automatic pressure control
Key specifications
Connection size: 1/2" suitable for standard plumbing fittings
Function: automatic water replenishment to maintain system pressure
Application: closed heating and hot water installations
Material: corrosion-resistant components for typical heating system water
Installation location: inline fitting between water mains and heating system
How to use
Install the valve in the incoming water line to the heating circuit using a compatible 1/2" threaded connection, following local plumbing codes and isolating the system before work. Set the desired system pressure according to boiler or system manufacturer recommendations. When system pressure falls below the set point, the valve opens automatically to admit water until the set pressure is reached, then closes to prevent overfilling. Periodically inspect for leaks and proper operation as part of regular system maintenance.
Usage recommendations
Use the valve with potable water supply lines and fit appropriate backflow prevention if required by local regulations. Verify compatibility with the boiler or heating system manufacturer’s recommended operating pressure range and perform routine checks to ensure the valve seals correctly and the system remains free of leaks.
