Safety valve MSW 3/4 inch x 1 inch 6 bar for DHW installation. 42425

Afriso MSW safety valve is a reliable protection for domestic hot water (DHW) installations against excessive pressure increase. It is a key element of every system, protecting both the tank itself and the other components of the installation – pipes, fittings, and, above all, ensuring the safety of users.

This angular valve, with a nominal diameter of 3/4 inch to 1 inch, made of brass, is characterized by a solid construction and precise workmanship. Its construction with a bellows seal ensures tightness and long-term trouble-free operation. The color of the nut – blue – facilitates the identification of the valve intended for protecting the DHW installation, which is particularly useful during servicing or modernization of heating systems.

The MSW valve has a relief pressure set at 6 bar, making it suitable for most standard domestic and commercial installations. The use of BSPP-G (ISO 228-1) cylindrical gas internal threads in both connections (3/4 inch and 1 inch) ensures easy and secure installation in existing installations. This allows installers to quickly and efficiently integrate the valve into the system without the need for additional adapters or gaskets.

This valve is designed for continuous operation and has been designed for long-term use. It meets safety standards, including the pressure equipment directive PED 2014/68/UE and has TÜV marking and a Type Examination Certificate issued by the Office of Technical Inspection, confirming its high quality and reliability. The maximum power of the installation protected by this valve is up to 100 kW (according to TUV) or 123.5 kW (according to UDT), making it suitable for various applications.

• Overpressure protection: Key function ensuring the safety of the DHW installation.
• Durable construction: Brass construction guarantees corrosion resistance and long life.
• Easy installation: Standard BSPP-G threads facilitate integration with existing installations.
