Safety valve MSS 1/2 inch x 3/4 inch 6 bar for solar installations 42330

Safety valve for solar installations – reliable protection of your system

This safety valve from AFRISO, model MSS, is a key element of every solar installation. It provides effective protection against excessive pressure increases, which is particularly important in systems using solar energy. Its solid construction and precise operation guarantee the safe and efficient operation of the entire installation.

The MSS valve is designed for both professional installers and end users. Installation is simple and intuitive, and reliable operation ensures that the heating system is adequately protected. The color of the nuts allows for easy identification of the valve's purpose in the installation.

Construction and application

The MSS safety valve is characterized by an angular (straight) construction and is made of high-quality brass, which ensures durability and corrosion resistance. It has internal gas tapered BSPP-G (ISO 228-1) threads with diameters of 1/2 inch and 3/4 inch, which facilitates integration with the existing installation. A silicone membrane ensures precise valve operation over a wide temperature range.

Designed for continuous operation in solar and heating installations, this valve is perfect for protecting devices against overpressure. Its relief pressure range is 6 bar, making it an ideal solution for most standard solar systems. It can also be used in domestic hot water installations. The maximum heating system power protected by this valve is up to 117.6 kW (according to UDT) or 50 kW (according to TUV).

Key features and benefits

• Overpressure protection: The valve effectively protects the installation from damage caused by excessive pressure, ensuring safe use.
• Durable construction: Made of brass, the valve is resistant to corrosion and mechanical damage, guaranteeing long-term reliability.
• Easy installation: BSPP-G threads facilitate quick and trouble-free connection to the existing installation.
• Wide application: Ideal for solar, heating and domestic hot water installations.
• Compliance with standards: The valve meets the requirements of the Pressure Equipment Directive PED 2014/68/EU and has TÜV marking and a UDT Type Examination Certificate, confirming its high quality and safety.
• Clear marking: The black knob makes it easy to identify the valve as intended for solar installations.
• Precise regulation: The silicone membrane ensures accurate valve operation at an opening pressure of 6 bar.

Remember to properly install the drain pipe with a constant slope and avoid installing shut-off fittings between the installation and the safety valve – this is crucial for its correct operation!
