This pressure-relief valve provides controlled overpressure protection for compatible Vaillant ecoTEC boilers, preventing excessive system pressure by venting when thresholds are exceeded. It is engineered for installation within domestic and light-industrial heating plant rooms where modest set pressures are required, and it operates as a safety component in pressurised hot-water systems.
