Safety valve for central heating. 1/2 inch female thread connections 3 bar 311430

Safety valve for central heating – reliable installation protection

This safety valve from Caleffi, with 1/2 inch internal thread connections and a 3 bar setting, 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 entire system. It is ideal for both new and modernized installations.

The valve is designed to work with various types of installations – heating, cooling and solar heating systems. Made of high-quality brass, it guarantees durability and corrosion resistance. The angular construction (right angle) facilitates installation in tight spaces.

Construction and application

The Caleffi 311430 safety valve is a spring-loaded device that automatically opens when the pressure in the installation exceeds the set value – in this case, 3 bar. Opening the valve reduces the pressure by releasing excess water, protecting the installation components from damage. The use of this valve is mandatory in every central heating installation in accordance with applicable standards.

• Wide application: ideal for heating, cooling and solar systems.
• Long-lasting construction: made of brass ensures corrosion resistance and long life.
• Precise adjustment: setting to 3 bar provides optimal installation protection.
• Easy installation: angular construction facilitates installation even in limited spaces.
• Compliance with standards: ensures safe and compliant operation of the heating system.

Key features and parameters

The valve is characterized by high precision and reliability. Thanks to this, both installers and end-users can be sure of the safe operation of the heating system. The medium temperature range is from 5 to 110°C, which allows the valve to be used in a wide range of operating conditions. The pressure class of the device is PN 10, which means that it is adapted to work at a nominal pressure of 10 bar. Both the connection and the drain connection are a cylindrical gas thread (BSPP) with a diameter of 1/2 inch (15). The set pressure is 3 bar, ensuring precise operation of the device within the set parameters.
