Safety valve MS 1/2 inch x 3/4 inch 6 bar for central heating installation. 42392

Safety valve for central heating systems

This safety valve from AFRISO, with a diameter of 1/2 inch to 3/4 inch, is designed to protect central heating systems from overpressure. It is a key element ensuring the safe and reliable operation of the heating system. The diaphragm design guarantees precise operation and long service life.

This valve is used in closed heating systems, compliant with PN-EN 12828, where water, a mixture of water and glycol, or other liquids from group 1 and 2 are used, which do not negatively affect the valve materials. Its installation is simple and intuitive, and the arrow on the body indicates the correct flow direction.

Key features and application

• Overpressure protection: The valve automatically opens, reducing the pressure in the installation to a safe level – 6 bar. This prevents damage to the boiler, pipes and other system components.
• Construction: Made of brass, which ensures corrosion resistance and long-term reliability. The angular (right-angle) design makes it easy to install in tight spaces.
• Versatility: Designed for continuous operation and compatible with hot water. It will work in both new installations and when modernizing existing heating systems.
• Safety: Has a bellows seal for increased tightness and reliability.
• Easy control: The valve knob allows manual control of its operation at pressures lower than the nominal opening pressure.
• Compliance with standards: AFRISO safety valves are tested by TȕV Rheinland and have a CE declaration confirming compliance with the pressure equipment directive PED 97/23/EC and Type Examination Certificate No. 373/CW/001/05 issued by the Office of Technical Inspection.

Installation and important notes

During installation, remember a few important rules:

• No shut-off valves: No shut-off valves (e.g., ball or check valves) should be installed between the installation and the safety valve.
• Protection from temperature: The valve must not be exposed to high temperatures during welding or soldering – installation should be performed after these works are completed.
• Flushing the installation: Before installation, the heating installation should be thoroughly flushed to remove any contaminants.
• Flow direction: Pay attention to the arrow indicating the flow direction on the valve body.

The AFRISO safety valve is an investment in safety and peace of mind – reliable protection for your heating system for many years of use.
