The Baxi 720777801 safety valve is a pressure-relief mechanism designed for closed-loop heating systems. Whenever internal pressure rises beyond 3 bar—a point at which components like the heat exchanger or pump are at risk—the valve opens smoothly to discharge excess and restore a safe regime. This component is found in numerous Baxi boiler families, such as the Ultra System, Megaflo 2, Neta‑Tec, EcoBlue (including ErP ranges), Duo‑Tec 2, and the Baxi 100 series, highlighting its versatility across product lines. Its thoughtful proportional response avoids sudden drops in pressure, ensuring system safety without compromising performance. Built for seamless integration, the valve supports long-term reliability when correctly fitted, but given its critical role, it should always be installed by a qualified Gas Safe engineer.
