Safety valve for central heating. Connections with 3/4 inch female thread 7 bar 311570

The CALEFFI safety valve is a reliable protection for central heating systems against excessive pressure. Made of high-quality materials, it ensures long-lasting and trouble-free operation. Designed for use in systems with a medium temperature range of 5–110°C, it protects against the effects of overheating and potential damage.

This valve is particularly useful in systems where pressure fluctuations occur, e.g., during water heating or heat pump operation. Thanks to precise regulation, it opens at a pressure slightly above the set point (+20%) and closes at a pressure below the set point (-20%), ensuring optimal safety and minimizing the risk of false alarms. Connections with a 3/4 inch internal thread facilitate installation and integration with the existing system.

Key features and benefits:

• System protection: Prevents damage caused by excessive pressure in the central heating system.
• Wide temperature range: Possibility of use in systems with a medium temperature from 5°C to 110°C.
• Precise regulation: Ensures accurate maintenance of the working pressure in the system. Opening occurs at +20% of the set pressure, and closing at -20%.
• Easy installation: 3/4 inch (ISO 228-1) internal thread connections allow for quick and easy connection to the installation.
• Durable construction: Made of materials resistant to corrosion and high temperatures, which guarantees a long service life.
• Nominal pressure PN 10: Ensures safe operation under standard operating conditions.

The CALEFFI safety valve with a 7 bar setting is an ideal solution for both new and modernized central heating installations. Its solid construction and precise operation guarantee peace of mind and protection against costly failures. The valve drain (also with a G 3/4 inch internal thread) allows for safe water drainage in case the valve is activated.
