Safety valve for central heating. Connections with 3/4 inch internal thread 3 bar 311530

Central heating safety valve – protection and reliability

This safety valve from Caleffi, with 3/4 inch internal thread connections, is a key component of every central heating installation. Its function is to protect the system from excessive pressure, ensuring safe and efficient operation of the boiler and other components. Its use in central heating, domestic hot water and cooling systems makes it a versatile solution for both professionals and home users.

Construction and application

The safety valve is designed to automatically relieve the installation in the event of exceeding the permissible pressure. This protects against potential damage to the boiler, pipes and other heating system components. Made of high-quality brass, it guarantees durability and corrosion resistance. The 3/4 inch internal thread facilitates installation and connection to the existing installation. This valve is used not only in traditional heating systems, but also in solar installations, where precise pressure control is particularly important.

Key features and benefits

• Overpressure protection: Automatically reduces pressure in the installation, preventing failures and costly repairs.
• Durable construction: Made of brass ensures long-lasting reliability and corrosion resistance.
• Wide application: Ideal for central heating, domestic hot water, as well as solar and cooling systems.
• Precise operation: Setting to 3 bar provides optimal protection for most standard heating installations – the valve opens at a pressure 20% higher than the setting and closes at a pressure 20% lower.
• Compliance with standards: Meets the safety requirements specified by Directive 2014/68/EU, confirming its high quality and reliability.
• Easy installation: 3/4 inch internal thread allows for quick and easy connection to the existing installation without the need for additional adapters (in most cases).
• Operating temperature range: From 5°C to 110°C allows operation in a wide range of temperature conditions occurring in typical heating installations.
• Pressure class PN 10: Indicates that the valve is adapted to work at a maximum working pressure of 10 bar – a standard value for most domestic heating installations.

Let us remember that regular inspection of the safety valve is crucial to ensure safe operation of the heating system!
