Sicherheitsventil 3 bar 1 / 2" De Dietrich 86665533

The Safety valve 3 bar 1/2" is a critical overpressure protection device for your heating system. Rated to release at 3 bar with a 1/2-inch connection, this valve automatically opens to relieve excess pressure, preventing damage to boiler components. If your system's pressure relief valve is leaking or not functioning, replacing it with this safety valve is essential for safe operation. It is a standard spare part for many boiler and burner systems.
