Safety valve MSW 3/4" x 1" 8 bar for DHW installation. 42426

Safety valve for domestic hot water – reliable protection of the installation

This safety valve from Afriso, model MSW, is a key element of every domestic hot water (DHW) installation. Its task is to protect the tank and the entire installation from excessive pressure increase, ensuring safe use and long-term reliability. Made of high-quality brass, it guarantees corrosion resistance and durability even in harsh conditions.

The MSW valve is distinguished by its angular design (90 degrees), which facilitates installation in tight spaces. It has threaded connections of 3/4 inch and 1 inch, compliant with BSPP-G (ISO 228-1) standard, which ensures tightness and easy integration with the existing installation. The blue knob not only facilitates operation but also allows for quick identification of the valve intended for protecting the DHW installation – this is particularly useful when servicing multiple systems simultaneously.

Key features and application

• Overpressure protection: The valve automatically opens at a pressure of 8 bar, protecting the tank and pipelines from damage.
• Brass construction: Provides high corrosion resistance and long device life.
• Angular design: Enables easy installation even in limited spaces.
• Threaded connections: 3/4 inch and 1 inch (BSPP-G) guarantee tightness and compatibility with most installations.
• Application: Ideal for securing domestic hot water tanks in homes, apartments and commercial buildings.
• Compliance with standards: The valve meets the requirements for the safety of DHW installations, providing peace of mind for users and installers.

This valve is designed for continuous operation and can be used in systems with a maximum power of 100 kW (according to TUV standard) or 151.8 kW (according to UDT). However, remember that the power of the installation should always be adapted to the parameters of a specific hot water tank and applicable regulations. The sealing of the housing further increases its reliability and extends the life of the device.
