Safety valve for central heating. Connections with 3/4 inch internal thread 2.5 bar 311525
Safety valve for central heating – protect your installation
This safety valve from CALEFFI, with 3/4 inch internal thread connections, is a key element ensuring the safe operation of central heating and domestic hot water systems. Its function is to protect against excessive pressure increases, which can lead to serious damage to the boiler and other system components. Thanks to its precise design and high-quality materials, this valve guarantees reliable operation for a long time.
Construction and principle of operation
The safety valve works in a simple but effective way. When the pressure in the installation exceeds the set value – in this case, 2.5 bar – the valve automatically opens, releasing excess pressure to the atmosphere. This prevents exceeding the permissible values and potential failures. It is worth remembering that the valve should be mounted in a place ensuring free water drainage in case of its operation. Made of brass, it provides corrosion resistance and durability even in harsh operating conditions.
- It has a 3/4 inch internal thread, which facilitates installation in standard installations.
- Set to 2.5 bar – optimal value for most domestic heating systems.
- Adapted to work in a temperature range from 5 to 110 °C, which ensures a wide range of applications.
- Withstands working pressure PN 10, guaranteeing safe use.
- Made of brass – corrosion resistant and ensuring long life.
- It is characterized by precise calibration: the opening pressure is the set value +20%, and the closing pressure -20%, which ensures stable valve operation.
This valve can be used both in new installations and during the modernization of existing heating systems. It is indispensable wherever effective protection against excessive pressure is required – i.e. practically in every home with central heating or domestic hot water. Installing a safety valve is an investment in peace of mind and protection of your heating system against costly failures.
