The Caleffi 577800 safety valve is specially designed for use with boilers. It plays a crucial role in protecting the central heating system from excessive pressure, thereby preventing potential damages. When the pressure in the boiler exceeds a preset limit, the valve automatically opens, allowing the system to vent and ensuring the safety of people and materials.
This specific valve is double-way, featuring two ports: one for the inlet of the medium and one for the outlet. This means that when the inlet port is closed, the flow is interrupted, while when it is open, the flow during inlet and outlet operations is the same. It is typically installed at the highest point of the installation and operates without the need for additional switches or valves.
